A "time to strike" stat doesn't make sense in the same manner that a speed stat does. "Time to strike" value of two different weapons can be the exact same value, but if range is double of the other, then the speed, which is a more useful value of accuracy is doubled despite the same value of "time to strike". The distance to the target also changes the time to strike in game as well. Speed is a characteristic that never changes, and is always a useful stat as well.
On another note, I would prefer a damage/flux stat instead of flux/damage, as the number displayed will correlate to the flux efficiency of the weapon.
