Velocity / Speed calculations are out
The calculations for the Alliance Challenger are out a by quite a bit for the Challenger (perhaps others).
By making a "racing" challenger, the max I can get Coriolis to is 220 m/s
Looking in game, my usual - non racing, hull tanked, tooled up Challenger makes 291 m/s (see attached pic)
They're incorrect for the Viper as well. When outfitting a Viper Mk. III for absolute top speed, as seen in this thread, the top speed is listed as 741m/s cruise and 927m/s boost, when according to the in-game shots (and also according to EDSY), it should be 745m/s cruise and 932m/s boost. I'm guessing maybe there's some sort of error related to weight calculations as going a step down on the power distributor lists the proper max speed (though weight seems to be reported right on the modules themselves).
