    Pretty new guy here with a general question about lies: When I read "30 -40% lie" does that mean the club normally commensurate with the distance will have a 30 - 40% distance penalty, or does it mean it can be expected to go only 30 - 40% of the normal distance?

    It means neither of those things.  It is just an indication of how bad the lie is ... starting from about 10-20% and going all the way up to 60-70% I believe.  It would be too easy (and unrealistic) if there was a simple mechanical formula.  Best way to deal with it is to practise hitting out of various lies with your clubs and balls and record the results.  Don't forget to experiment with the spin settings too.  This is what makes the game interesting for some ... and torture for others :)

    What about the 25-30 lies?  A 12 percent deduction for those as well?  Usually its the first cut of rough.

    I play 25-30 rough a little different.  For shots up to and including 8 iron (150 yds), I only add a yard or 2.  Once I start getting to the mid- and long-iron shots, I start adding a little bit more.  

    Again, my suggestion would be to play with it and see what you think.  Make notes.

    There is a “time honored” basic math formula that is generally accurate for shots of 100 yds or more - 30/40 rough, distance times 1.1, 40/50 rough, distance times 1.2. These work fairly well for basic shot setup, but you also have to factor in elevation, roll out, wind. Less than 100 yds, depending upon your wedges you can be fairly accurate with + 2 - 4 yds for 30/40; 40/50 takes some practice because results are not always consistent and vary from situation to situation. For up close shots at the green, the flop works best as it will stop the ball fairly well. Classic example, WC hole 13 with either pin, the upper one especially. Not uncommon to be long off the green in the 30/40 rough. A pitch will land you close, but will not stop. With a proper set up, the flop will. Good idea to map your wedges for flops from the rough. Good place to practice hitting from 40/50 to the green is Merion #11. Hit your tee shot over the creek into the deep spinach. Then use your 64° wedge and practice hitting out.

    This post is golden.  I am landing my 30-40 and 40-50 shots within 10 yards of the pin reliably well.  What about the 25-30 lies?  A 12 percent deduction for those as well?  Usually its the first cut of rough.

    Is there a way to upvote your post?  I would love to!

    on 25-30 I add 2% to the stated distance to the pin. comes out pretty close in most cases,

    30/40 means ball is covered into grass that percent, 40/50 basically half ball covered. On 100 yard wedge shot, 30/40-- add 5 yards; 40/50 add 10 yards.
