Calculating experience values in Scarlet Horizons

Update: I’ve converted the XP advancement system so that it’s not fractionally based.

Of course, treasure XP may still be fractional since 1 spent gp translates to 1 XP.

If I recall correctly, a day or two ago, I began spit-balling a way to determine fractional experience values for defeated monsters in Scarlet Horizons.

Here, I refine my thinking a bit more:

0.001 (per Hit Die) If AC < 7 add 0.00010 If AC < 4 add 0.00015 If AC < 1 add 0.0002 Special ability (attack or defense) add 0.0003 per ability/quality

I've attempted to apply this to aboleth spawn.
