I'm new to this game and being a huge nerd I decided to try and figure out what the measurement values of each disk was in relation to how far it would travel with each flip assuming that each flip was not altered by slippage of the disk. At first, I wrongly assumed that it would merely be diameter of the disk multiplied by the number of flips. Ultimately that formula was incorrect because I didn't factor the value of thickness (1/16) into the equation. With that being valued in here is what I came up with:

Small disk will travel 2 and 5/32 inches with each flip ( 55mm)

Medium Disk will travel 2 and 9/16 inches with each flip (65mm)

Large disk will travel 3 and 5/16 inches with each flip (85mm)

Hopelfully you guys will find this information usefull and give you a tactical edge in your future games

Edit: Metric in brackets

If you really want to memorize measurements, it might work out a bit better to estimate how far along the range ruler a disk of each size can travel, since you are actually allowed to check range in game with that. I wouldn't pull out a ruler and measure, nor would I allow my opponent to do so, but the range ruler is valid per the rulebook.

I actually know roughly how far a disk can travel in term of long-range, medium range, short-range on the range ruler, but I don't allow myself to measure unless an actual shot is going to be taken. Measuring for movement just feels like it is a bit against the spirit of the game. It also feels more real to prohibit non-shooting measurements--you wouldn't really stop in combat to measure the distance between yourself and an enemy, you would eyeball it and then make your decisions from there. Of course, you wouldn't really measure before you shot at someone either, but you get my drift...

Just my two cents; maybe I just like the uncertainty when I try to close out a long charge.

That said, this is interesting information, thanks for figuring it out!

I agree and would be against the use of rulers or tape measurements in actual gameplay as well for the same reasons that you stated. The reason I posted it is in practice and for evaluating potential disks to add to my army. In practice, if you know the exact distance a disk will travel, it can help you to eyeball more effectively in a game. For evaluating disks, I think that mobility is important and with different disk sizes and number of flips, it can sometimes be difficult to see what disks have the greatest reach; with this simple formula I can quickly figure out how far a disk will travel against other disks and make my decision based on those values.

I agree, it would definitely be a useful bit of information for eyeballing a charge. It was interesting to see the size difference between small and medium--it was not as great as I expected.

The Vassal tool is also a great way to represent disk movement and see relative battlefield coverage between different disks, though it does leave out the edge of the disk in between flips if memory serves.

I could have sworn that one of the tournament FAQs did say you can't use the range ruler to try to measure distances. it was a discussion that came up before the first official tournament and a lot of those people were like "It isn't against the rules, I don't care if it is against the spirit." So FFG came out and said no.
