I should be working but I’m not...

Animals at least seem to have a formula for conversion.
The DV (I assume this is a dodge) is based the best I can tell on this:
DV= 10+size+dex+"Natural"
Natural DV bonus seems to come from this chart:
Level D4 D6 D8 D10 D12
1 0 0 +1 +1 +1
2 0 +1 +1 +2 +2
3 +1 +1 +2 +3 +3
4 +1 +2 +3 +3 +4
5 +1 +2 +3 +4 +5
6 +2 +3 +4 +5 +6
7 +2 +3 +4 +6 +7
8 +2 +4 +5 +6 +8
9 +3 +4 +6 +7 +9
10 +3 +4 +6 +8 +9
11 +3 +5 +7 +9 +10
12 +3 +5 +7 +9 +11
13 +4 +6 +8 +10 +12
14 +4 +6 +9 +11 +13
15 +4 +7 +9 +12 +14
16 +5 +7 +10 +12 +15
17 +5 +8 +10 +13 +16
18 +5 +8 +11 +14 +17
19 +6 +9 +12 +15 +18
20 +6 +9 +12 +15 +18

As monsters are all 8 HD creatures just cross index the #of HD (level) with the 8HD column to get the Natural DV bonus.
This seems to get me very close on 80% of all animals and monsters. One thing on the chart that should be changed is at 1st lvl the 8HD modifier should be changed from +1 to 0.
Damage across the board seems to just do up one dice. i.e. D4 is now D6, D6 is now D8, and so on.
As for Animal DR...I don’t really see the pattern there. But I've not really look or plotted it out yet.

Good luck
