    Ok, I have a question here, I have been playing more and more this game, and enjoying more as well. I am facing a problem that I don't really understand.

    Here is random number to clarify how i do my shot calculation:

    Hole 145y away, front wind 10y, hole elevation 15y. so If i understood how to calculate the shot correctly, it should be 145-10+15= 150y.

     

    So i take a club that give max 150y, and 100% power, and ding the shot, and yet sometimes it over shoots are undershoot by as much 10y sometimes.

    Maybe i am missing something here lol, and your help is needed lol

    First, hole elevation is not in yards, but in feet, some would say 3 feet make a yard but I doubt it sometimes, and I am sure the rest.

    Front wind 10 y? Wind is in miles per hour, one measures distance, the other speed. You can't just add here and there, you are lucky you only went 10 yards over and even luckier if it was less.

    The other parameter is your clubs, and balls, and the DING!!! that it makes when you hit it where it says "HERE".. you haven't seen the word, but it's in very small case engraved in a line in the power bar(called meter)< I just magnified it for you, but is there(have you ever seen the small prints in legal documents you sign?). Provided you do DING, then your shot should be good, but there is also something called "lie", that sometimes lies, but refers to where your ball sits It could be rough, brush, mulch, and... the others forget  them, you won't like to hear about them. You will need more distance from bad lies, and the lies lie, so be ready to feel deceived.

     From the tee you may get a little bit (or big) more distance than from fairway, that has to do with the F.... Ding thing, plus, all the other aspects, and... well there is topspin and backspin, and they may make you gain or lose distance to. The backspin is applied by moving the green dot in the ball towards the bottom and topspin... well, where else could it be? Some balls really have a very good spin, the free balls are just a diarrhea going down your legs, you can't stop them, the only thing you can do is wash well after all the shi.. has stopped and do your best  with the meter again so you can really stop it before you dehydrate.

    After you spend time practicing,  cursing and thinking you know it all, or a lot... you may regret the day you took that Imodium and didn't dehydrate to death, or at least, stopped eating.. you will realize it is late and you are hooked, still getting the shots of a hack sometimes, and hoping a meteorite would make the hole bigger, or thinking after all... that is a damn mother f... good game that you hate, but can't quit... why am I 10 yds passed the hole? I still ask myself that question from time to time, guess someone has a better answer for me,.. please, give me some advice when you learn.

    SOYEL1:

     the free balls are just a diarrhea going down your legs, you can't stop them

    I'm so sorry to read this only now. Really great. From this side of the pond I'm used to  blow on balls to make  'em stop.

    Nevertheless one formula reassured me about the existence of God, and spurred me on developing software about:

    new distance = (distance+elevation/3) x ((wind speed x 0,004)-1) for tail winds.

    and

    new distance = (distance+elevation/3) / ((wind speed x 0,004)-1) for head winds.

    on this page: vincereconwgt.blogspot.com/, on the right column  you'll find the script, named CADDYZ. You need only to write down in the order the wind speed, the wind angle, the hole distance and the elevation and click on the button "vai" to find  the shot distance and the deviation from the flag stick. Actually it is not that efficient but still we'll have some figures to debate about while sitting on the closet.

    Hole 145y away, front wind 10y, hole elevation 15y. so If i understood how to calculate the shot correctly, it should be 145-10+15= 150y.

     

    the shot i would play is as follows:

    145, plus

    .. 7yds for 10mph headwind, plus

    .. 3 yds for elevation, plus

    .. 5yds for full b/spin

    total: 160yds 

    .. using full backspin .. but i play with Burner 2.0 irons & Nike balls for stopping power .. that shot will put u within 2 yds from the hole if u ding it ..

    just an example .. there are many

    EDIT: another 2yds for elevation .. my mistake

    I actually make it 156...7 iron full bs would be right on the pin ;) with 2.0s and lvl71 Nikes

     

    145 plus

    +5 yards for elevation change (15 feet uphill %3)

    Into a 10 mph wind from that distance I'd add 6yds seeing as your shot is 15 feet uphill ;)

    To be clear here, make sure that elevation is not expressed in feet when you look at it. Most of the elevation changes are measured in feet and you have to divide by 3 to get the yards. Not paying attention to this will really throw your shot off. In your example, if that 15 yards was actually feet, you would have over corrected for it by 10 yards, adding 15 instead of 5.

    Also, when you say front wind, keep in mind that unless that wind is coming directly at you, the adjustment for it isn't going to be quite as large as the total speed of the wind. Spin on the ball will also have an affect on the distance, too. Back spin usually shortens it.

    My results with a tail wind  (angle 90°) of 10 mph, distance 144 yds, 15ft of elevation is 144,75 with a deviation of 0sticks

    sure 15ft=5yds

    By this logic he should have doubled the wind affect?? IMO the elevation was in feet and he figured yards. 145 yards away, 15 yards (45 feet) up won't be getting flown by a 150 yard shot.

    I think you're right but his example is a little off. I have a feeling the elevation correction might be messing him up.
