I have the su 22 M3 and I have managed to grind my way all the way up to rank five in the USSR tech tree. I’ve already got a couple jets and I’m not against just grinding the rest of the tree out like normal. But would it be faster to use the Su-22M3 it’s only one rank below the most efficient progress

Nope, Su-2M3 is a rank VII aircraft, so it’s only effective at grinding out rank VI-VIII aircraft. So trying to use to grind rank V would put you at a disadvantage.
