How Far Did You Just Wheel?!?!?!?!?!?!?

In every game of Warhammer I have ever played or seen played, nobody really takes correct measurements of the movement it takes a unit to wheel.  There is always some level of estimation involved.  Bending of measuring sticks or tape measures is the normal course.  Sometimes people use "wheel templates" manufactured by GF9 or other companies.  But they would only be accurate for units of a particular width (the wider the unit, the more movement it takes to wheel) and I don't even know what unit width they are calibrated for.  I have also seen some pretty heated disagreements about how much movement it takes to execute a particular wheel when it can make a difference between a failed charge and a successful charge.

So how much movement does it take to complete a wheel?  I spent a few minutes and set up an Excel spreadsheet to do the calculation, and the result is below.  The table indicates the distance (in inches) it takes to complete a wheel based on the width of the unit and the angle of the wheel in degrees (angles are listed in 5-degree increments.  Print out this table and you can use it in conjunction with a protrator to measure your angles (the cheap plastic kind you used back in elementary school would work fine) and you can measure the movement of your units (and those of your opponents ...) much more accurately.

Wheel Template

Just added the template in JPG format as an attachment to this page.  May need to be re-sized when printing.  Per Sanders, try 137%. 

This changes things

The standard cav wheel using 6" as per the GF9 template is totally fudging the movement phase!   Even a 5 wide unit is taking nearly 2" of leeway.  The 6 and 7 wide cav units are outright abusing the movement phase...

HA!

This table appeals to my analytical tendencies as a scientist, but if I actually pulled out a protractor at a tournament and proved my opponent’s charge failed by 5 degrees... well, he just might beat me up and take my milk money, after taking a huge dump on my sportsmanship score that is!

I wouldn't care if it was

I wouldn't care if it was close, but I've seen people try to pull huge wheels with wide units when there is no way they have the movement to do it.  And I think a lot of times when that happens, the perp knows on that he's doing something sketchy.

GF9 arcs are for 100mm as

GF9 arcs are for 100mm as they show 5" for 90 degrees as I recall. I generally prefer to measure my wheels one inch at a time if it matters. It can matter a lot for 7 wide cav units.

 

Cool protractor brah
