Percentages In The Rough

Could someone please explain how to hit according to percentages in the rough/sand ((62%-82%), etc…? I understand it means the density of the rough, but what do these percentages in calculating your shot accurately?
Does anyone have a good formula, special trick?

Thanks

its a penalty for landing in those zones, the values given are off 100 %

I’ve been useing 20-50% rule of thumb. ADD 20% distance for rough, 30% for semi rough, 40% for deep rough, and 50% for sand.
So if I have 20ysd from rough hit 22yd power. If I have 20yds in sand, hit 30yd power etc.

Thanks a lot for this! I do something similar, but this seems more accurate. I’ll definitely try it!
