OGC reference for average GP / level?

[Planesdragon]

Has anyone come up with a good OGC mark of a character's average GP / level?

I could fire up my spreadsheet and just multiply each creature's average gold by 1 2/3 (assumes 50% retention of treasure), but I'd like to see what else is out there first.

Ok, I'm impatient...

Based on the formula above and the SRD:

Lvl / GP
1 100
2 500
3 1,300
4 2,500
5 4,100
6 6,233
7 8,900
8 12,366
9 16,900
10 22,900
11 30,633
12 40,633
13 53,700
14 71,033
15 93,700
16 123,033
17 160,366
