scottxxy: This is great for aiming, but how much does a crossing tailwind assist you?
This is from my blog. It has pictures too to help show the calculations...
HOW TO
CALCULATE ARROW PLACEMENT FOR WIND SPEED
Wind is a big headache for
any WGT player. Using the old "Kentucky windage" method is great, if
you any not in a hurry to advance beyond Master. (Kentucky
windage is the practice of applying a horizontal adjustment of the point of aim
for wind without the use of any physical or mechanical adjustments on your
club. In other words, making a guess.) I have experimented with a few of the
methods recommended by top WGT players, then have come up with the following method.
This is my own design, but if there is something similar out there I apologize
for not giving proper credit since it would be coincidental, not intentional.
THE
PROBLEM:
If the wind, for example, is 3-5
EAST (E>) and the distance to the pin is 40 yards, your arrow
adjustment is not the same as the adjustment you would make if the pin is 140
yards away. Pretty obvious, right? More complicated is...what if the wind is 3-5
SOUTHEAST (SE\|), or 9-11 NORTHWEST (NW|\) ?
How many DIRECTIONS are
there? My design uses the 8 listed here. There is NORTH; NORTHEAST; EAST;
SOUTHEAST; SOUTH; SOUTHWEST; WEST; and NORTHWEST. Are there 8 others? Does
WGT have NNE; ENE; ESE; SSE; SSW; WSW; WNW; NNW? Maybe, but for simplicity
sake, and my lack of intelligence, I am only addressing the original 8. Also,
how much difference at 140 yards away is the calculation different for NNE and
NE? It can't be much, and if it is for you then you don't need to read this
(and I'd love hearing from you).
MY DESIGN:
Arbitrarily, I have selected 180
yards as my base. If the distance to the pin is 40 yards, divide 40 by the 180
base (40/180=.22222). Then multiply this amount by the wind. If the wind is 3-5
E>, then multiply the .22222 * 3 (the first number WGT gives for wind on
the hole) = .66666. This .66, or 2/3's of a yard, is the amount of yards you
move the arrow over to compensate for the wind.
How to view the green to adjust for
2/3's yard: Switch
from FULL SWING to CHIP or PITCH, then go to REVERSE
VIEW (click on the camera on the lower right of your screen). You now have
a view of the green from the flag point of view, and if you click on the arrow,
a grid appears. This grid is 1 yard square. As you can see, the flag is in the
center of the grid. Moving your arrow over to the middle of the next grid would
be 1 full yard so you would have to estimate where .66 would be. Can you be
exact? Yes. Use a regular ruler on the screen, or use an online window ruler
(see my other blog for download information).
What would the adjustment be if you
were 140 yards away?
Again the calculation is basically the same. If the distance to the pin is 140
yards, divide 140 by the 180 base (140/180=.77777). Then multiply this amount
by the wind. If the wind is 3-5 E>, then multiply the .77777 * 3 (the
first number WGT gives for wind on the hole) = 2.33. This 2.33, is the amount
of yards you move the arrow over to compensate for the wind. Notice that with
the extra yardage the distance from the pin increased proportionally.
Another issue that happens with the
increased yardage is the fuzziness of the grid. All the dots and squares become
a big blurry mess. This can be easily fixed. Right click just under the hole
and click on ZOOM IN. Still not clear? ZOOM IN again...and again
if need be. Then you can move the arrow to the grid you select.
How do you adjust the arrow if the
wind is from the 4 odd directions (NE; SE; NW; SW) ? Again the calculation is basically the
same. If the distance to the pin is 140 yards, divide 140 by the 180 base
(140/180=.77777). Then multiply this amount by the wind. If the wind is 3-5
SE \|, then multiply the .77777 * 1.5 ! The 1.5 number is
calculated by assuming the wind of "3" is now half (since SE is
halfway between S and E. So the calculation is .77777 * 1.5 = 1.17. This 1.17
is the amount of yards you move the arrow over to compensate for the wind. Also, for NORTH and SOUTH,
your calculation ADDS TO your yardage or SUBTRACTS FROM the
yardage to the hole. Again the calculation is basically the same. If the
distance to the pin is 140 yards, divide 140 by the 180 base (140/180=.77777).
Then multiply this amount by the wind. If the wind is 3-5 N /\, then
multiply the .77777 * 3 = 2.33. The 2.33 REDUCES the yardage to the
hole. It would be 140 yards MINUS 2.33 = 138 yards (rounded up).
I asked a great WGT
player how he had such a low "putting average per hole". Their answer
was "It's easy, put the ball close to the hole. The closer you are, the
less putts you take." Makes sense. Hope this wind tip helps.
