This from the Tweet below:

1º diff between face and path on a driver creates 4% curve i.e 12 yards at 300. 1 dimple off centre strike does the same.

If the numbers are right, i t's a miracle I can drive the ball straight the number of times I do - not 300yds though :-)

I've never really believed the bit about being off by a dimple and the errors it supposedly causes. I mean, either that's accurate or we're all a hell of a lot better than we give ourselves credit.

I agree I hit it all over the face and pretty much not that far off line.

same here...but the 1 degree thing sounds more reasonable although I think this might depend on the type of golf ball played as I was under the impression that some balls spin more than others.

Using http://www.csgnetwork.com/righttricalc.html it seems like a swing path that is 1 degree In/Out with a club face square to the path will produce just more than a 5 yard push/pull at 300 yards.

I haven`t studied trackman data or the ball flight discussions in much detail, but based on the above, it sounds like you want to be about 2.3 degrees In/Out with the club 1 degree towards the target relative to the swing path to get the ball to go back to the target.  Does that sound right to any trackman experts out there?

That's assuming the ball flight is straight. If the face is open 1 degree to the swing path, some spin is also going to be created. Probably not enough to bridge the gap between 12* and 5* though. I think. :-P

For gear effect, TrackMan says that a 1/2" miss with a driver will tilt the spin axis about 20% and the same miss with a 6 iron will tilt it about 7%.

So, put another way, for that 6 iron point on the curve -- if you were 3 degrees open to the path and hit it 1/2" toward the toe, you'd get a dead straight shot.

I think.

Yes, I was assuming a straight pull or straight push.  I wasn`t trying to imply that these results should be the same as a with a straight path and 1 degree open/closed club face.

AM I CORRECT TO ASSUME THAT A CENTER HIT WITH A CLUB FACE SQUARE TO THE SWING PATH WILL PRODUCE A STRAIGHT PULL OR PUSH (OR IS THERE SOME OTHER FACTOR THAT TRACKMAN DISCOVERED)?

Based on the below, it looks like 1 degree open/closed (to the swing path, not target) is worth about the same as 1 degree in/out with a club of roughly 25 degrees.  With a driver (10 degrees loft) a 4% shot bend would produce 12 yards of draw/fade at 300 yards (assuming I`m understanding the term shot bend correctly) so this confirms the tweet in the OP.

I think I should have said 3.3 degrees in/out as I forgot to subtract the 1 degree for the face not being square to the swing path.  I have read that the direction the face is pointed roughly 85% controls where the ball starts- for this calculation I am assuming that the ball starts exactly where the face is pointed (2.3 degrees off the target line and 1 degree off the swing path)

Thanks, that seems consistent with what I was saying about a straight push/pull.  I tried google already, but is there somewhere on the web where I can plug in the numbers like you did?

Based on what has been posted above, I find it interesting that the same clubhead path and face angle is going to end up in different spots relative to the target depending on the loft of the club. i.e. a guy who always swings with a club head path 3.3 and face 2.3 to target is likely to see his driver end up fading back to the target but see his wedge start on the same line but fade less and stay almost 4 yards left

      A Novice Journey to Building a Bag. (Help Appreciated)

      By retoid ·

      Thank you, currently I only had the 2, 3, 6, 7, 8, 9 irons in the bag. I was never finding myself in a situation to use the 4 and 5 so I dropped those a while ago. The 60W is what I've been practicing with the most in the back yard, but that's only with short chipping. I don't think I've ever practiced hitting my wedges at 80% - 100% apart from yesterday. Maybe I should be doing that more. Generally I would be using a 9 iron if I was out about 75 yards or so. I am not really sure I understand your mention of the 60W and 3H. Aren't these going to be giving me completely different results? Unfortunately I am not able to adjust the loft on the hybrids I have. I looked into the Shot Scope H4 you suggested and this seems really neat and handy, however I am struggling to understand how it works. Am I correct in assuming it doesn't track the ball distance until you hit the ball a second time? Say I drive from the tee and walk up to my ball, tag the next club and hit the ball. Is it at this point when I tag my next club while standing next to my ball that is knows the distance? Thank you, I am going to give the local shop a call and check their prices and see what they can offer.

      Is This Club Blatantly Sandbagging?

      By Ty_Webb ·

      Do you know what their handicaps are? The handicap system isn't perfect and given the higher variance from higher handicaps, I think low handicap players would be expected to win maybe 60% of their matches? I'm not exactly sure what that number is and it will vary with the handicap difference, but if they're generally very low handicaps, then they might be at 60% likely to win a game. Given it's 16 vs 16, that's a lot of games to win. If it's 60%, then that's around an 80% chance that they'll win a given match. At 80% chance of winning, 21 wins in a row is about 1 in 108 times. Pretty unlikely, but not unheard of. It's pretty sensitive to what that individual win percentage is too. If it's 65%, then 21 wins is about 1 in 9. If it's 55%, then 21 wins is 1 in about 5,700. Clearly it's not as simple as this because that win likelihood is going to change match to match as they play lower handicap teams or higher handicap teams, but I don't think it's a "yes they're cheating" thing at all.

      I'll be honest, the only reason the 2 iron was in my bag is because I tend to hit the ball into the tree's fairly often. And I was using it to help me keep the ball very low to get out of the tree's while avoiding getting much loft to hit branches. I guess I can drop the 3H as well. Would it be wise to give a higher loft fairway wood a try as well, something like a 26 degree? I believe there is only one golf shop where I live that has a golf simulator and trainer. I see they offer free fitting with a purchase from the fitter. I'll have to check how much they charge without a purchase, I've read a few stories about fitters on this forum that just wanted to sell the person the most expensive clubs and that kind of deters me a bit. They do offer lessons as well. I'll give them a call and ask them a bit more about these services. Thank you!

      The Stack System - A Conversation on Gaining Swing Speed

      By DeadMan ·

      Here is a description of all the programs:  Programs & Training Programs and Training TheStack is a personal swing-speed trainer for golfers. Initially, each golfer is piloted through a series of swing speed tests to generate a force-velocity profile of their current swing. Qualitative data is... I think cruiser is meant for maintaining speed and flex can do more than that. But I'm just basing that on the descriptions that I linked.

      Is This Club Blatantly Sandbagging?

      By jsgolfer ·

      Both @DaveP043 and I play in our interclub matches every year, and have been team Captains as well.  There are always a few courses, mine is one, that win a lot of matches (we've won twice in the last 7 years), and we've been labeled as sandbaggers.  However, I really think that our course was rated too low (our greens just never seemed to get factored in enough), and thus our Handicaps were always a stroke or maybe 2 above, what they would've been if the course was rated higher.  And then when we went and played other courses, their slope and rating were much higher than ours, and sometimes I would get a 2 or 3 stroke bump on top of that.  It was definitely an advantage.  However, this past year, our course was rated again and the slope has gone up, so we'll see if we continue to have the same benefit.  Season starts this Sunday for us.
