Doing a quick and dirty model in NEC gives the following:

160m - 25º
80m  - 25º
60m  - 24º
40m  - 21º
30m  - 19º
20m  - 16º
17m*  - 14º & 52º
15m*  - 47º & 13º
12m*  - 41º & 12º
10m * - 36º & 12º

Ground loss erosion out past the ends of the short radials on the lowest
bands listed will eat at those 'twenty-some' degree numbers. They will
effectively end up being more like 30-degrees--a good round average
number to use.
