Q on stacking of toughness enhancements

[tc12]

So I looked at my Dwarf's HP and it seems higher than I thought it should be. Better than the other way around, but thought I'd ask:

I have Dw Tough I-II and F Tough I-II (and the Toughness feat obviously). I was expecting 5 HP from each of the "I"s and 10 HP each from each of the "II"s. That would be (5 +10) + (5 +10) enh and at my current lvl (9) 11 more from the feat for 41.

Contrasted would be if no racial and instead Fighter Toughness I-IV, that would be (5 +10 +15 +20) from the Enh +11 feat for 61.

Interestingly, with Dw II and F II I have the 61 HP so am getting (5 +10 +15 +20). Is this a bug or is is supposed to work this way? What happens when I get my next toughness enhancement (III of either Dw or F)? Since I've already been given a 20 for "level IV" type enh, I'm not sure what to expect. If it moves me back to (5 +10) + (5 + 10 +15) I'd actually lose 5 HP.

So I'm guessing the 5th level just starts at 5 HP again. (5 +10 +15 +20) + (5) Then 10, 15, 20 if you progress to all 8 combines levels of Toughness. Can anyone confirm? I'm certainly not planning on 8 levels of toughness, and if the next costs 3 AP to get only 5 HP then those diminishing returns would me wonder if it's worth it. Right now the 50 HP from II/II seems like a pretty sweet spot for only 6 AP spent. That's way better than the 5 HP / AP spent I thought the last update was bringing.

You've messed up in your calculations somewhere (or your character is bugged).

I have a Dwarven Paladin with Paladin Toughness IV and Dwarven Toughness III and they work exactly as you originally thought.

The Toughness Feat gives you 2+Character_Level extra hit points (So, +3 at level 1 and +16 at level 14).

Each Enhancement of either flavor gives you 5xEnhancement_level extra Hit points (So, +5 for level I, +10 more for Level II, or +15 total for having Level II).

If you have both Dwarven and Fighter Level II's that is +15 + 15 = +30 extra hit points.

Is it possible you forgot your Heroic Durability when figuring out from where your Hit Points came?

Ya, Heroic Durability fits the unexpected 20 HP perfectly. Good catch.
