Hitting Pure Flattened Movement?

I've been experimenting with an anti surfer gun which decays on shots and on hits/ bullethitbullets , its working reasonably well vs top bots with flatteners disabled. (Not good enough yet though...) I am suprised the anti surfer gun isn't used vs most surfers, but then again I've only been doing tests vs DrussGT, Diamond, and other high ranking bots... The difference I see is that a pure flattening bot would change its profile every wave, while a pure surfing bot would have the same profile until hit.
