my method is fit 60 angle distance power
1/4 - 1.1
1/2 - 1.75
3/4 - 2.2
1/1 - 2.55
5/4 - 2.85
2/1 - 3.15

wind - 25
wind direction - 45 degree
distance - 1 sd
0 wind power - 2.55
result - 25 x 8 = 20 + 60 angle = 80 angle with 2.55 power *mostly i reduce or add little power when with ultra strong wind* so i use 80 angle 2.5 power will hit 1 sd enemy v-.-V
