Well, assuming you heal 10% of your HP as a base percentage:

0.1 (base percentage) x 1.8 (power strength) x 560 (your health in this case = 100.8 (seems about correct)

As for me, I just use the base health of 300, with a power strength modifier of 102%, so:

0.1 (base percentage) x 2.02 (power strength) x 300 = 60.6, which is what I'm seeing.

TL;DR: I think it's safe to say that the self-heal is at a base of 10% of your maximum health, modified by power strength.
