Cosmic horrors are 0.4062 peds at stage 1 and hermits are 0.75 peds.

Not done the others yet.

This does not equate to the x16 lowest hp theory it seems, by the way (unless I have misunderstood).

Also, I use the reciprocal set multipliers which are easier to remember of 1, 1.6, 3.2 and 4

According to my sheet, based on LavaSparks work, when I put in 650 HP for Mob with least HP I get the following values:

Rank 1 - Set 1 1 0.40625

Rank 2 - Set 1 2 0.8125

Rank 3 - Set 2 3 0.76171875

Rank 4 - Set 2 4 1.015625

Rank 5 - Set 3 6 0.76171875

and so on.

The Calculation is as follow:

Least HP divided by 16 gives Skills in Pec.

so in the case of Cosmic Horro it is

650 / 16 = 40.625 Pec = 0.40625 Ped

So in line with the formula here in the thread.
