The CR and DR bonuses for HD/level progression doesn't seem to be occurring for the levels in character classes the modified creatures have. I think this is because the increases use PREHD instead of PRELEVEL.
OK, it looks like all Hit Dice, both racial, and from classes should be considered for these abilities.
Okay, did you want to handle it, or should I just tackle it withthe PRELEVEL proposed?
Go ahead. PRELEVEL sounds right.
All PREHD entries for the templates we had in B1 and CE are now updated to the new standard.
DR seems to be working fine.
CR is working fine except that the second CR +1 for the half-fiend is kicking in at 6th level instead of 5th (source material here: http://paizo.com/pathfinderRPG/prd/monsters/halfFiend.html#_half-fiend says CR +2 for 5-10 hit dice for the half-fiend.)
