Some more numbers. Someone please correct my math if I did this wrong.
Rough Live Caps
ss 93
sj 78
fly 59
Rough Beta Caps and Rough Percentage Increases
ss 120 +30%
sj 102 +30%
fly 93 +58% (average over 90 seconds, Fly goes UP on shorter trips)
Again, someone please correct me if I'm wrong, but if I'm right Fly is getting almost TWICE the buff the others are getting.
EDIT: I think some of my numbers ARE wrong, so disregard while I look some stuff up.
Ok, I see my error. My numbers are correct IF we ignore Live Afterburner. We can't fairly do that, but we can recognize that on Live flyers must take an additional power to get to their higher cap, on Beta they can do it just with slotting and no OAS.
So I add another line:
Live Fly+AB Cap is 88
Beta again is 93 (average over 90 seconds)
approximately +6%
So it IS fair to say that for actual travel (at least 90 seconds), Fly is getting a much smaller buff than the others IF you have AB on Live. However, that difference gets less and less as the trips get shorter. For a 30 second trip, Fly will actually be very slightly faster than SJ and will have been buffed. And of course if you DON'T have AB on live you are getting a BIG buff.
In Combat speed of course Flight is getting a big buff and the others are getting nothing.
