Why ranges in http://www.holdemresources.net for the same hand in old calculator and in new beta calculator are different!?

Take this hand from HerekPL-s blog for example:

Poker Stars $11.28+$2.82+$0.90 No Limit Hold'em Tournament - t150/t300 Blinds + t25 - 4 players

MuckChicken (CO): t2520
Hero (SB): t4590
MavisHandbag (BB): t3760

Pre Flop: (t550) Hero is SB with A 9
2 folds, Hero raises to t4565 all in, MavisHandbag calls t3435 all in

Old versions calling range for BB here is 6.6%, 77+ ATs+ AQo+, but
new beta one is 77+, AQs+
