Vulcan, some remarks:
The g10 outaccelerates tif only starting both at very low speeds and with no alt room for the tiffie. At med or hi speeds and going a bit nose down the tiffi will win the acceleration race (lo alt).
Tiff can roll with 190A5/8 using that "e-burning" rudder, but the E lost by the 190 in the rolling scissors (using only elevator and ailerons) is greater than the lost by the Tiff adding rudder plus pulling (elevator, ailerons and rudder). The tiff quickly compensates the roll difference after two rolls. And most important, due the tiff armament, it can stay far from the 190 (500 yards or more), so, compensating even more the 190 rolls.
And yep, the tiff bleeds E (logically), but much less than any 190 or 109. Try one of these and you'll be horrified.
Dora can catch a tiffie only with a little alt advantage, else the run would be ethernaly long.
