  No English major myself and calculations irk me, but I'm firmly with K7 on this one.

  I hear ya there.  Grip it 'n' rip it.  Half the time the wind doesn't quite do what you expect it to anyway but most if us shrug it off and move on to the next hole.  Some may try improving the accuracy of their shots by going to 5 decimal places, sure ain't my way though.

  nanstar:

  Wind may or may not affect your shots, but it will have some effect on them.

  I guess what you mean is the wind will always have some effect on your shots, just not always as big a one as expected.  Perhaps if you'd added the words the way you calculated after the words shots it may have been clearer.

  I'll give you a 2- because you're usually a quiet and well behaved student.

  I am at Legend level, and have hit a wall as far as scoring goes. During matches I hear members talking about my math was off or dropped my calculator. I s there a way to calculate your shot with math? I've asked but all I get is silence. Need your help.. Thank You Ramjet007

  Every shot requires a math calculation- however with Driver and an open fairway, basically I just aim for driver distance and then to offset the wind and err my misses into the wind. Since almost 90% of your drives hit the fairway, you already know this.

  Your greens in regulation stat is not bad, 80%, however your average distance to the pin is 14 feet, while good players are around 10 feet and elite players 9 feet- which means all things equal, closer means more birdies/eagles. To improve this stat, aside from knowing how far your clubs go with x ball and x spin; as explained above- you must adjust for wind and elevation for a "true distance", then execute the shot after factoring hole "peculiarities" as well as knowing - for example- better short (ie below hole) than long (above hole). All designed to give you more "makeable" birdies.

  Finally, your putting stats show a lot of room for improvement; e.g., your one putt % is below 50- where very good players are above 60 and the best even approaching 70% one putts. Basics of putting do involve math, but very simple math :distance plus or minus elevation, some wind factor on links courses (20 plus mph) and then your green speed calculation. The rest is learning how to aim and when to off-ding. Most good players do the latter part by feel and experience. 

  The forums have loads of opportunities to learn the more advanced nuances of the game and practice/competition are the keys to ingraining that knowledge. Hope I don't sound too preachy!

  Know the course and winds. Winds on courses like St. Andrews and RSG will generally affect your shot more than a course like Congressional or Olympic due to trees or rather the lack of trees. I feel WGT has programmed the affect of the winds to be affected by trees just like in real golf.

  It's a pain in the a$ and that's why lots of people use calculators such as Kats (https://drive.google.com/folderview?id=0B8zXgJL4jcQeaEI1NHBRc2N4c1E&usp=sharing) or Sgt. Bilko.  If you're doing it in your head I'd suggest using Sine and Cosine.

  15 degrees = .259,  30d = .505,  45d = .707,  60d = .866, and 75d = .986.  So 2, 5, 7, 8, and 9 are close enough.  10 Mph wind blowing towards 1:30pm on a clock would be 45 degree angle.  10*.7 =  7mph of adjusted tail wind and Side wind.   If it was 1:00pm that would be 30 degrees.  So 10*.5 for side wind = 5y.  and 10*.866 for tail wind of about 8.5y.

  For every 10mph of head wind per 100y its around 5.8 or 6 yards of added wind.  For every 10mph of tail wind per 100y its around 3.9 or 4y of subtracted wind.  So after you get the adjusted distance from the previous paragraph you have to to even more math to adjust it to the correct distance. 

  For Tail wind @  50y*.2,  75y*.3,  100y *.4,  125y *.5,  150y*.6,  175y*.7,  200y+*.8.

  For Head W  @  50y*.3,  75y*.45, 100y*.6,  125y*.75, 150y*.90, 175y*1.05, 200y+*1.2

  I’m a couple of years late here with the OP and he’s probably already discovered this by now but for others Googling this, visit MistressCossete’s profile page and copy and paste her blog into a word doc and study study study, and practice practice practice

  While I agree with practice, practice, practice, you couldn't pay me to read all that stuff. Or more to the point, no one would be willing to pay me what I would want to read all that stuff. 
  
  I've seen shorter dissertations. :-) 

  C'mon Professor!  Surely you have read worse!!

  I copied/pasted it, then went through quickly re-arranging the order and condensing some on the fly before going into detail.  There is some useful stuff in there - it does take a bit to get the meat uncovered.

  Maybe you could write your own?

  Or get a grad student to do it?

   

  LOL
