Hybrid tank stamina effect

[Stonewallx39]

Does anyone know the calculation for how much hp increase with each point of stamina per level for Pally and SK?

I think it's an equation. Something along the lines of hp=level(.02xstamina). I can't find anything in game mechanics.

I have inconsistent play time and i'm wondering if I end up soloing a good bit with my future SK if it would be worth it to add strength vs stamina for extra dps. I just don't know how much sta actually increases hp at lower and middle levels.
