This really bothers me because it means the game is using the mass for something, we just don't know what it is...since some damage types like missiles are backloaded, every second can count (nothing worse than seeing an enemy cap jump from the gravity well with 10 HP left)...I agree though that at the small percentages used for Vasari armor techs, the effect would hardly matter...if large changes of mass just don't work then I guess we'll never get mass changes that could actually make a noticeable difference...
If that happens send some Bomber-loaded Carriers after it 
Any suggestions on how to test changes to acceleration rates? How long does a ship normally take to accelerate to full speed? How long for max turn speed? Would the TEC thruster upgrade even be worth it if it gave a 100% increase?
I was definitely disappointed with my 90% reduction test, as it clearly proved mass reduction doesn't improve the arching turn situation (unless you want that minefield cleared, though that works perfectly even without further help)
Maybe I'll at least test TK Push, but since applying the original value every 0.5s barely caused a frigate to budge I think this effect does exist.
Oh I agree...and given how phase space is portrayed with Vasari techs (buildings with barriers, scout ships), travelling in extra dimensions seems more likely than bending space...
...which ends this discussion until the Chaos come over and enlighten us regarding the nature of Phase Space.
