Hello,

I am looking for some help evaluating results from a launch monitor session. The images below were taken during an outdoor lesson. I think it was a flightscope.

Two clubs, two different quality of strikes. Not sure if this can even be answered.

My questions are:

What is most important when looking at this data? How do you compare different clubs?

In my example are both results close or is one performing significantly better? Or If the human variables were closer would one have an advantage?


First driver was a G400 Max. I think the spin was 3000 ish. I was hitting some low on the face. However, I am unsure to what degree that can affect spin. I know it increases it.

Second image shows the results of a Callaway Rogue. The spin was 22XX but That was a perfect shot for me.

Wife took the photos so we might be missing some data. Best coach ever :)

Had fun on the monitor I just wanted to know more about what I was looking at.

First you aren't a wrx'er because it's not 195+MPH ball speed.  

Past that.  Distance is carry distance, roll is roll, total is total distance.  Club head speed is club head speed, ball speed is ball speed off the face. Easy right?  To me, one of the most important (beyond right left and consistency of distance) is smash.  Smash factor is the quotient of ball speed by club head speed. In essence, it's the efficiency of your swing.  The closer to 1.5 it is, the more efficient.  So, that's how the 98mph swing was shorter in distance than the 96mph swing. Probably something to do with hitting it low on the face or something. Clearly much more technical answers out there but I'm a big believer in smash.  I look for 1.4 and above on longer irons, and 1.5 on driver.

Overall your strike on the rouge was much better than the ping based upon ball speed vs swing speed (same info that 2nd poster is talking about). Based upon THESE swings you were more efficient with the rouge. Overall much better results.

I don’t have two with closer numbers to compare. I thought there might be a way to subtract or add from the smash to estimate the ball speed or carry.

Appreciate the help. I will keep practicing. Hitting the center helps.

You can divide ball speed by smash to get to your swing speed, but you have all three of those numbers anyway.

Carry is mainly a calculated function of ball speed, launch angle, and spin.  Although you're missing those two key metrics the smash in the latter is much better, indicating a much better strike.  Because those 3 numbers relate (smash indicates the efficiency you got out of the strike) you can see in the latter screen shot that you got more carry distance even though you had a 1.5 MPH slower swing speed because your strike was better.

Strike was better with the second club because either:
> A) Your slower swing speed indicates you were swinging more in control on that shot (i.e. you were better, but the club)
> B) The second club (due to shaft, clubhead, or both) just suit you better, therefore you were able to put a better strike on the ball

If this was the only data I had available to me and I was making a choice between these two exact configurations, I'd be taking the second one.  Better strike, better efficiency, better result.

You somewhat already answered your own question begore you ever asked it. Ball speed and club head speed.  Thatís your efficiency and sign that the contact was in the right area, maybe not perfect, but in the right area. Once you start straying away from center, ball speed goes down, your efficiency goes down, and you are more likely to have all the other numbers skewed by bulge/roll of the face, gear effect of the head, etc.

Most important area to work in first is contact location, those numbers help to verify that, then you start working on the other ones to tune.

Thank you

You got some good replies already, but to me this clubs seems to be standard, and thats based on the huge difference in PTR value (smash factor)

If both clubs had the right play lenght and total wgt, only shaft model was different, the difference in PTR value would have been way smaller.

Next...dispersion.
About 20 yards right of targetline is NOT a fairway hit on the courses i play, so my conclution is, you had a lucky strike in terms of smash factor on one of them, but non of them is a good fit for you, they was most likely tested at standard playlenght who is way to long for most players.

Go and see a real club fitter, trial and error with standard play lenght want help you to find a club that works as it should in your hands
