Well, cruise speed of the various types of planes involved in a strike is a matter already heavily discussed.
With all due respect, m'Lord, whilst that is so, the critical fault line is if the one bomb group that cruises 60mph slower than the other n groups, is the one selected as raid leader. That will stuff up a lot of subsequent co-ordination DRs.
I have my own ideas about how the raid lead group is selected, but it's (anecdotally informed) guesswork at best. Experience, skill, leader aggression and air rating, that air group bombing accuracy stat (is that squadron related or pilot related or both?), they all sound like things the program might check. But I don't think the criteria for selection of the raid leading group has ever been de-classified.
