Is SI or SE better for Corsairs?

It's something like that, but I'll need a Buccaneer to help me do the tests with SI.

According to my new guess about speeds, Cannon (3) should be 633.75 milliseconds and Cannon (2) should be 585.

I'm not sure whether the 30-ms rounding occurs within the game or between the game and LazyBui's packet tools, though. If it's the former, then these numbers would obviously not be exact.
