TM SLDR - Launch Monitor Stats

[Foxholer]

Duncan,

I think what happens is that, while the launch is initially higher, the lower spin produces less aerodynamic lift. So higher at the start, then flattens - so the peak is about the same - then drops similarly. Just like PX (and other) iron flight is meant to be. Sound reasonable?

I'm still slightly confused about the difference in heights between mab's 78' (26 yards) and the 36-43 yards that the_coach states. Where is that figure coming from? Certainly not the (2009) figures I've seen of 31 (PGA) and 25 (LPGA) - albeit with quite low launch angles.

In terms of flight and peak heights between 'new $' high launch angles and 'old $' lower launch angles, that's it. lower launch takes longer to hit peak but then descends sooner at same more or less descent angles, higher launch takes shorter time to get to similar peak but then travels further at that height, descends therefore later (in elapsed time) but still at similar descent angles.

I probably didn't explain properly in my first reply exactly what I was meaning and referring too, my post then wasn't meant to be picking anyone up about anything they'd said, just trying to clarify something, but that didn't turn out to well, so sorry if added to confusion
My peak height references are made relative to my own ball speed numbers, 36 being relatively normal give or take, 43 being the maximum I'd tend to get from either 'new high launch' or the 'older previously perceived ideal lower launch angles'. Peak height is relative to the amount of energy you transfer to the ball.

Ah! Perfectly clear now, thanks :thup:

My, no, referred to a point of if you are looking to achieve a high launch a +AoA which the OP wanted to achieve (rightly from the tee with a driver) it isn't the case that the back spin has to go up too. When comparing a high launch against what used to be thought of as the old lower then ideal launch angle.

so basically your No isn't in reference to the post you have quoted at all ...

I've now re-read your post #22 and I think we are all in the same place now

What is your typical ball speed may I ask? And also your AoA?

Like Fox mentioned above, 36-43 yards seems a high 'normal' window when, with a decent ball speed of 150mph and decent launch conditions, I'm achieving only 26 yards peak flight. I would assume must have quite a bit faster ball speed and be at 6* or more AoA?

The numbers, I was trying to both convey my average, plus what I found over time to be the highest peak height I tend to have.
I put them up, given that folks seemed to be a bit confused that the peak heights changed dramatically from the lower launch numbers previously thought of as ideal (9, 10, 11, 12d) and that the peak heights would naturally be a good deal higher with the 'new ideal' of the higher launch angles (14-17d). I have found this is not the case they are the same pretty much and most other folks I've observed also looking in to this with Launch Monitors have found the same, as far as I'm aware.

The numbers are all particularly relevant to what I found through week to week (or so) observation through the last 2 years or so with LM.
Most of that time of course being at at the lower launch end of 10 thru 13 and when I was just monitoring what was then going on thru a number of parameters with my own numbers in practice.
Now of course over the last few months that's changed in to me looking into the 'numbers' with the 'new' higher launch information coming out.

One thing to keep in mind, in the maybes holy grail search for higher club head speeds and higher ball speeds and a higher launch and higher AoA. Is that you only get the best 'numbers' whatever these all are, with a correctly stuck shot, ball connected at the sweet spot of the club.
(One thing of note here is the actual sweet spot of most if not all drivers is not the one indicated by the design symmetry on the face, the true sweet spot is in an asymmetric position, not bang central)

36/35 yards PH is what I've found over time to be approximately my average, 43 yards the highest.
So complete range over time guess is 29/30 ish to 43, but none of these numbers affect descent angle over much really, range 129d to 142d - ish.
Rollout I've found to be slightly longer with the higher launch and lower spin rates when compared to lower launch rollouts.
Carry and overall distances I've found to be a deal further with these higher launch low spin rate combo's, dispersion pretty much unchanged given as I said before solid contact from sweet spot, and a good neutral swing path.

The 'old' lower launches which go with slightly higher spin rates (2550-3500 guide range) reach PH later in the flight, higher launch low spin rates reach PH sooner in flight but still carry flatter for longer, so the greater distance.

My AoA between +3 to +6 on a normal basis of 'the well struck ball', my BS average window mostly between 160 -164 mph, there's sometimes a mph or so either, off or onto those figures, just depends how well the particular swing is sequenced and whether it's connected right out of the 'button'.

Thanks coach.
