Movement rates for smaller character with these traits is not calculated properly. All movements other than Flight should be calculated at 1/4 for Little characters and 0 for smaller characters. For Flight it needs to be based off (Run-1) x Rank and not the normal calculation of Run x Rank. Look here for an example: Neutrino. He is Miniature at Rank 3 and his move speeds are 1 and his Flight is 15. That should be 0 and 12 respectively.
For Larger characters, the flight seems to be off by the 1 point for calculating it as if you are big. Otherwise the other movements seem to be correct. Here is an example: Biggie
Edit: Sorry, it looks like the other movements are also off by the +1 for big. His normal run speed is 5+1 for big and the calculations would be x20 for size which should be 120 for run and he has 100.
