Default GWX attack scope scale

I have a question regarding the attack scope scale in GWX for using the mils scale for range finding.

It's now 10X on high power, I know, but what is the angle represented by each scale division now?

In the manual for 6x, each small division represents 1/4 degree and each large division 1 degree, but i presume this is different now.

Has anyone made a mils chart for all the ships?

I'm talking about measuring the length of the ship to get the range.

Steel Beasts has an excellent tutorial in range estimation.

Joe, check out this post by danmir in this thread

I, too, was wondering about the scale, so I tried to puzzle it out. I took empirical data at the 10x mag, and charted it in excel. Basically I took measurements with the stadometer at 15, 13, 12, 11, 10, 9, 8, 5 ticks. I'm at work now, I did the charting at home, but the excel sheet linear estimation of the degrees per tick was about 0.156 degrees per tick.

I thought about this, and I have concluded that in GWX at 10x magnification, there are 0.15 degrees per tick. Reason?

- At 1.5x mag, they are 1 degrees per tick. You can verify this yourself, and it makes sense it would work this way.
- At 10x mag the scope tick scale does not stretch or anything.
- Key info: 1.5 / 10 = 0.15
- 1 degree tick gets subdivided by the ratio of the magnification, thus 0.15 degrees per tick
- I think the game engine funny rounding/flooring for the displayed angle moved my measured data slightly off accounting for the 0.156 linear estimation.

Heibges, this may be what you're looking for

Thanks jmr, that's exactly what i needed to know, and of course it makes sense.

I figured out that you can use the slide rule side of the whiz wheel to calculate range from mils readings if you can't be troubled with the recog manual and stadimeter. I jeust needed to be sure of the x10 scale

I was looking for a chart more like:
......Range.................1200m............600m
Ship
Medium Merchant..........6ticks............12ticks
Large Merchant............7ticks.............14ticks

I uploaded one I had made a few months ago here:

Even though the UZO (6x) and the Periscope (10x) are different scales, the "tick marks" are spaced differently such that the conversion is the same for those two.

Actually, Greyrider made some charts just as you described. I have them and if you like I can email them to you. Just PM me your email address.

@ dmlavan

Are you sure about that, as this contradicts Danmir's conclusions

to summarise, from the SH3 manual, p39

Optic------------small marks---------large marks

Peri (low power)----1degree----------5degrees
obs=x1;att=x1.5
Peri (high power)---0.25degrees-------1.25degrees
obs=x4;att=x6
UZO (x7)-----------0.2 degrees-------1 degree
Danmir found that
GWX attack scope --0.15degrees-------0.75degrees
x10

but you are saying that GWX attack scope and UZO have the same scale. Which of these two versions is correct? The results only differ by .05degres, so it's possibly just an oversight but it seems to me that Danmir must be right unless the GWX team also adjusted the scale. However if they did that, then i'd expect it to stay at the original 0.25 degrees.

I can't vouch for what they programmed w/ GWX and if one of the team members can jump in they can probably give a better answer, but I did this based on a test mission with numerous ships at various ranges using the "map contacts enabled" feature so I could compare w/ the actual range. For the Attack Periscope (1.5x), I got 1 mark = 1 degree, and for the Uzo and Attack Periscope I got 1 mark = 0.15 degrees. I've used this fairly successfully for manual targetting.

The fact that you got 0.15 for both suggests that the UZO was also changed to 10x.

Does anyone know if that is the case?

The UZO is indeed set to 10x in GWX for the same reasons as the attack scope and as stated in the manual.

Regarding all optical magnification changes in GWX... only the upper limits were changed. Lower limits remain the same as stock.

excellent, thank you! I'd somehow failed to pick up on the change to the UZO
