Why not just argue that you were accelerating to improve handling in order to avoid the pothole instead of trying to fudge numbers to "prove" your case?
I would actually recommend finding some concrete literature that states that a motorcycle can be swerved and turned more stably and safely while the speeds are higher because the forward momentum helps maintain the bike's gyroscopic tendency to stay up. If you can back your argument with this kind of documentation, and you can get them to believe that you really did only speed up to get around the pothole and then slowed back down, you should be ok.
However, if you insist on coming up with the numbers, the only place I can think of is Microsoft Excel. That's right, you get to do a little math and write the equations yourself. I'm an engineer and therefore I'm a total nerd, so this stuff interests me. If you'd like, PM me and maybe I can help.
