Battle/exploring time proportion on Hard and PotD

[Phenomenum]

Just thoughts...
I have done some tests on Hard and PotD difficulties, relating time i spent in exploring and combat.
 

Test slice: 1-st act until Defiance Bay (killed all enemies on every one map encluding 1-st level of Od Nua, Raedrick keep and so on).
 

Hard: Time in combat - 8.5 hours (ingame statistics)

PotD: Time in combat - 10.9 hours (ingame statistics)

 

Nearly +30% combat time on PotD (for me, anyway) compared to Hard. And this is significant shift from exploring to combat action.
