No. It really only gives you an idea of how deep the rough is: it's a percentage of how much of your ball is buried. You'll have to figure out how much effect it may have, there's no easy answer except: the lower the percentage the less the effect and the lower the loft the more the effect. 30/40 rough you can still get a decent shot with mid-high irons; 40/50 is tough and above that it's a punched wedge to nearest bit of fairway
