The 20 part powers are something like this:
1/4 SD: 85, 2.8
1/2 SD: 80, 2.83
3/4 SD: 75, 2.86
1.0 SD: 70, 2.91
1¼ SD: 65, 2.98
1½ SD: 60, 3.07

The windchart I use is just the normal banpao windchart(s) from long ago:

(ignore the power levels written here, they're mostly bad. But the charts are good)
