before we start understand that these results have come at many tedious hours of testing and trial and error, these findings can have +/- 5% error so do not take these calculations as the word of god, though it is close enough
Note all testing was done at 65FOV

Hensoldt scope
*** Second Focal Plane Scope ***
Error  +/- 3%
being the second focal plane, the zoom doesnt affect the reticle pattern which means when you zoom in the mil angle between each dot increases or decreases, dont wrap your head around this too much as we are only working with 5 to 1 conversions, a little background on the Hensoldt scope, in reality it is supposed to be a First Focal Plane scope, also mils in reality the scope would have to be zoomed to 12x to do estimation of a scav assuming average height of a scav is 1.7m so since the scope is only 4 x and 16 x, we will take 1.7 x 16/9, so when fully zoomed we have to assume a scav is 3022mm or 3.02M tall.

                                                   Math                                                       
3022 or 3000(rounded) is height of target in mm
3000 = H = Target Height
X = Millr tall
Distance to Target (Meters) = D

Equation
H / X = D
3000 / X = D

Example
3000 / 9 = 333M
in the picture the true range was 339M

Quick Reference
Zoomed        UnZoomed                    
300m = 10 Millr        300m = 2 Millr
250 = 12 Millr        250 = 2.4 Millr
200m = 15 Millr        200 = 3 Millr
150 = 20 Millr        150 = 4 Millr
100 = 30 Millr        100 = 6 Millr

Kentucky windage
when zeroed at 100m, each mil down or up will be +/- 10m so if you want to hit a target at 120m and you are zeroed at 100m, zoom the scope in and aim with the second dot down.
100m = 10m
200m = 20m
300m = 30m
ONLY WHEN ZOOMED

 

 

EOTech Vudu


*** First Focal Plane Scope***
Error +/- 1%
being the first focal plane means as the scope zooms in it also zooms the reticle which means that the scope is alwasy at the same mill

When the VUDU is zoomed, each tick line is equal to 5 MOA, dont worry about MOA vs Mill but we will figure this out the conversion for moa and meters is going to be 87.3
so we will take 82in x 87.3 = 7150(r)

Math
[height of target = H = 7150] Converted
 [(MOA Marks) x 5] = X
Distance to Target (Meters) = D

Equation
7150 / X = D

Example
7150 / 52 = 137.5M
in the image you will notice i was still able to estimate a slight offset of range due to size of reticle, in reality, the shot was 134M and the target should be 53.14 MOA Tall

Escape_From_Tarkov_Screenshot_2019_06.26_-_19_47_36_13.thumb.png.056c043e443c4ec7fccc4103b28f5f6e.pngEscape_From_Tarkov_Screenshot_2019_06.26_-_19_51_16_08.thumb.png.79b1ccf0c0c8c0c6a3e31d4efda0a198.png

Quick Reference
Zoomed
300M = 23.8 MOA
250M = 28.6 MOA
200M = 35.75 MOA
150M = 47.6 MOA
*!*100M = 71.5 MOA*!*

Unzoomed concerns
understand that the reticle can only measure 50MOA so the 100m increment is useless, when zoomed out, you should have your scope zeroed to 100m anyway. 

Escape_From_Tarkov_Screenshot_2019_06.26_-_19_45_23_15.thumb.png.634e3cc5102c86dbcc7a8ee03cea7f70.pngEscape_From_Tarkov_Screenshot_2019_06.26_-_19_45_30_63.thumb.png.8390c25faed8aaef8199b07948c41804.png

when unzoomed, the reticle is off, when unzoomed the reticle appears to be only 25MOA tall and when zoomed it will be 50MOA, so  when zoomed out a target that takes up the entire + of the reticle will be 286m,

 

 

Valday PS-320 1X-6X


*** Second Focal Plane ***
Error +/- 2%
the Valday if very similar to the Hensoldt scope in that they are the same focal plane and both use mills as the distance guide. HOWEVER, in between each dot on the valday zoomed in is 2.5 mils, the easiest way to get around this is to change our estimated target height from 3022mm to 1199.7mm, lets round this to 3000mm and 1200mm. the Valday has the disadvantage in that is also can only zero out to 200m so after that you are on your own, lets start with the math

Math
target height = H = 1200mm
Millr tall = X
Distance to Target (Meters) = D

Equation
1200 / X = D

Example
1200 / 4.3 = 279.06M
note that in the picture the target is actually 278.15M away and my estimation was actually fairly accurate.

Quick Reference
Zoomed
300M =  4 Millr
250M = 4.8 Millr
200M = 6 Millr
150 = 8 Millr
100M = 12Millr
Unzoomed
why are you using this???

Kentucky Windage
Again, when zeroed at 100m, due to each dot being a 2.5 mil increment, we will have similarities and differences from the hensoldt scope. below we will be explaining the adjustment for the first Millr from the center of the reticle going up and down at that range Zero. so again if we are zeroed at 100m and our target is at 125M when zoomed in we will just aim with the 1st Millr down and we will hit our mark.

100M = 25M
150M = 37.5M
200M = 50M 
250M = 62.5M
300M = 75M

again the fact the valday cannot zero past 200m does make this point a little redundant.

 

 

i will be doing more testing and will be happy to take suggestions on different optics to test, so far these are my findings, until i have developer confirmation on the height of a scav model in in game statistics i can not do anything else with this i have yet to test the Burris Tac-30, Leupold Mark4, Nightforce ATACR, March Tactical, and i dont consider the pso, or the pu's to be worth effort of time

Awesome to see someone else looking into this, I've done a fair bit of work on the subject myself. (funnily enough I also play on 65 FOV)

I worked backwards assuming that all the scopes were SFP and not set to their scaled magnification , and disregarded the height value as being static, choosing instead to assume that the mil/moa scales were correct and simply living with a changing  variable for each optic as our "scav height"

In going in this fashion the only reticles that have a constant scav height are the mk4 LR and the Vudu.
(they end up being 136 and 138 cm values)

Oh and something I will disagree with you on is the FFP vs SFP stuff.

"a First Focal Plane scope, also mils in reality the scope would have to be zoomed to 12x to do estimation "

SFP reticle scale is shifted , FFP reticle scale is constant.

First focal plane has the erector assembly between the ocular and reticle.

Second plane has the erector after the reticle , between the ocular.

Probably just a typo.

probably again this was alot of info that i dumped quite quickly so yeah

a better way is to enable option for manual bolting so you can actually use the hit mark/dust to determine how off you are from the mark.

Dude i really think that manual bolting has to be implemented... It would be a great change in sniping. Maybe you can keep fire button pressed and bolting on release

Not sure you know this or not, but if you hold the left mouse button when firing, you don't bolt until you let go.

so lame by me😣. i was reading the post and thought it wasn't implemented yet.... I own one to the devs!!!

thanks mate

First of all, thanks for your work.

i'm still try to find the right measurment and noticed that you made a mistake.

The EOTech Vudu works with MIL not MOA. I'm reffering to the service-side of EOtech.

Short: the whole DOT when zoomed in is around 1MOA or 0,29 MIL.

From the center of the DOT to the first thick line is 1MIL.

Problem is the unknow high of scavs.

The math behind this is breaking my head, because the high of scavs is an unknow variable that seems changing with every optic.

Now i finaly managed to do the math-work correct.

Assuming that the distance your shot traffeled is right and we will round this up to 135m.

If the EOtech Vudu is function like the real on with MIL-Measurement (MRAD not MIL/Strich) than:

H x 1000 / Y = R

H= height of target in m

Y= count MIL marks = 10

R= 135m (rounded)

-> H = 135 x 10 / 1000 = 1,35m

 

And now the trick with MOA -> 1 MRAD (MIL mark) = 3.44 MOA

-> 10 MIL Mark = 34,4 MOA

according to a marine the formular for MOA would be

H (in inch) = R (in yards) x Y (MOA) / 95.5 (this was given me as factor)

H = 147,6 x 34,4 /95.5 = 53,16 inch = 135m

 

-> so this tell us if an average SCAV is 1,68m or rounded 1,7m high and our formular give us 1,35m back, the zoom isn't work as in real life. The zoom-factor is than in game 7,55 in game and not the expecte 6x as described in game (having FOV 65)

Another day full with formulars.

 

Based on my calculations, I am currently assuming the following situation:

A) FOV doesn't affact zoom for now (patch 0.12.5x) - testet with several FOV and the same scops at same range.

B) It seems that the devs using the following MOA-measurement-forumluar: H x 95,5 / MOA = R (H in inch and R in y)

 

So knowing that 1MOA  should be 1.047inch at 100 yards

and

optics over 10x magnification-level mostly use this at full magnification-level

than:

March Tactical 3-24 x 42 FFP is at 16x

     [ when 1MOA eguals 1.047inch at full 24x magn.]

     - it has only 1 magnification (zoom) - this

so the Nightforce ATACR 7-35 x 56 FFP is at 24x unzoomed and 36x zoomed in

     - ingame the scope is not ffp but sfp because the crosshair doesn't change!

     - problem: the scope does only support 35x magnification

 

I know that 1MOA with March Tactical eguals 1.5 MOA at unzoomed Nightforce and 1 MOA at unzoomed Nightforce equals 1.5 MOA with Nightforce zoomed in.

All in all, it seems that there is one scope in game as a hidden factor that influence all other scops with there magnification lvl.

 

It would be nice if someone could forward this the the devs.
