On the 262 issue, the 262s cost perks and B-17s do not. As long as the "average" 262 cannot earn enough perks to replace its self in B-17 kills, then the number of 262 flying against B-17s should go down once the perks run out. So what you have here is a war of attrition. On one side you have a big pile of fighter perks that have accumulated over the years, and on the other side you have the patience of the bomber guys to fly for hours with little chance of surviving.
I would think that if someone (Lushe?) where really interested and had the time, they could check to see how many B-17s where killed by 262s and the number of 262s killed by B-17s; then, based on average perk costs, determine if the 262s killed enough B-17s to cover their losses. If the 262s are covering their losses, then the number of 262s the B-17s are seeing today will either stay the same or go up. If the 262s are not covering their losses then the number should go down once the perks run out.
If it weren't for the cartoon airplanes it would almost be real.
