Also, movement speed is rounded to even percentages on the client, but the cheer may actually be 3% in the server code. Similarly, Bolter's Roll looks like only even percentages when measured in isolation on the client, but may actually have odd values in there that we just can't experience because of the rounding.

That makes me wonder if you could find the extra percent by testing bolter's roll percentages with the cheer. If the server is only rounding when it sends the packet with your speed, it's feasible that the cheer could be used to measure bolter's roll more precisely. It'd also establish that they didn't directly short you on the cheer.

Checking with targetinfo,

Snake Eye-Random Deal-Bolters Roll+8:
Roll 1, Cheer and no movespeed gear: 140%

Snake Eye again, Doubleup:
Roll 2, Cheer and no movespeed gear: 140%

Edit, all of that is wrong, cheer is an 'active' effect not gear, clearly.

Moving cheer to the active portion:

(100%+gear%)*(1 + roll%) + 0 + 2~3% + 0 = final

You should be able to see a difference under these conditions:

Gear +8%
Bolters+8 Roll 1 (+38%)
1.08*1.38 + 0.02 = 1.5104 (+50%) or 1.08*1.38 + 0.03 = 1.5204 (+52%)

Gear +12% or +18%
Bolters+7 Roll 9 (+32%)
1.12*1.32 + 0.02 = 1.4984 (+48%) or 1.12*1.32 + 0.03 = 1.5084 (+50%)
1.18*1.32 + 0.02 = 1.5776 (+56%) or 1.18*1.32 + 0.03 = 1.5876 (+58%)

Retested, it does appear to be 3% based on this check:

Gear +18%
Bolters+7 Roll 9 (+32%)
1.18*1.32 + 0.02 = 1.5776 (+56%) or 1.18*1.32 + 0.03 = 1.5876 (+58%)

Targetinfo gives +58% movespeed under this condition

ok, so most of the time it gives 2% but in rare cases it gives 4%!

I knew there was a reason I full-timed it, lol.
