Difference between Experience and Heroic ability??

[magnate]

Is there a formula for HoF places? I once had two commanders, 141xp and 2 kills, 142xp and 2 kills, and *between* them in the HoF was someone else's hero with 75xp and 31 kills, or thereabouts. That makes one kill equivalent to some massively non-integral number of xp ... or are different kills worth different (undisplayed) numbers of points?

Also, is there any difference between normal (recruited) commanders who get into the HoF and are thus "heroic", and the "national heroes" who sometimes show up? Do the national heroes get non-random abilities, or something?

Do either type get more heroic abilities the more time they spend in the HoF?
