Random Chance of Reversing

I think I might have something which keeps full functionality but also reverses with a 0.08 probability. The problem is, it also reverses with any enemy bullet fire, so should I decrease that probability? I'm thinking down to about 0.06, since there needs to be a good chance of a direction change happening during the flight time of the bullet, but there was already one at bullet fire time so we don't want it reversing all over the place. Or should I stick with 0.08?

Go ahead and test with 0.06 or 0.05.
