For those who read/commented on my previous thread last week

(can be seen here http://forums.golf-monthly.co.uk/sh...or-figures-how-accurate-are-they-really/page2)

I went for my 3rd of 5 sessions on the Launch Monitor (confirmed as a GC2) on Tuesday this week.

The settings were set with a wind of 0mph and a tee box lie.

These were the full figures for the clubs that I tested (see attachment)


So what if anything can be taken from this ? I'm not looking at the total distances as there is no such thing as run at this moment. The carry distances I have used last weeks figures and this weeks to try and give me a rough indication for them.

But if anyone is aware what all the other figures are all about and can see anything that would set alarm bells of can they advise me ?

Cheers

Chris

Can't seem to get a decent size on the picture so I have just added the averages for each of the clubs,.

So if I'm reading right

4 iron ..... Carry 180.62yds ..... Total distance 211.45yds

6 iron ..... Carry 166.69yds ..... Total distance 188.76yds

7 iron ..... Carry 163.69yds ..... Total distance 180.57yds

8 iron ..... Carry 150.87yds ..... Total distance 167.05yds

PW ......... Carry 125.95yds ..... Total distance 138.90yds

only thing i can see is the 6 and 7 irons are going a very sim distance and you are getting 20 yards roll with most of those, Id be a little put off with a 7 iron running out an extra 20 yards. Also your 4,6 and pw SS and distance are the same as mine but the other 2 clubs go further. I couldn't tell you why though

If I've read it right, and see numbers as this
It looks like, as with most golfers, you probably have decent gaps through your set, until the longer irons, which most golfers (A) struggle with and/or (B) aren't consistent with.
7 iron 163yds
6 iron 166yds
4 iron 180yds ..... All carry
Not enough gaps, distance wise from 7 iron upwards.
A 163yds 7 iron is very decent, so you could take a guess it's a confident club to pull out.
But I'm still a bit curious as to the 13yds (run) difference between carry and total with a PW.....??
Would be hard to land on, and stay on a green, surely......??

My next step would be
Go get all my lofts and lies checked, and altered, if need be.
Then see figures on next session.

To be honest
If I was seeking my yard ages
I would just get an average of my "carry" distances, for use on course, most then know what sort of run out you would normally get
As when looking at your figures, with average carry, and average total, it looks like you wouldn't be able to hit a 6 iron into a green, land it on, and stay on green, not with a run out of 22yds.....!!

Impressive numbers! Seem to roll out a bit as Patrick said. Is that because the GC2 was set to 'tee box' and would the total distance be different if your hitting into a green? I'm not too familiar with launch monitors !

As others have said, the carry distances don't seem to be a nice spread through your bag.

The other thing that leaps out at me is that the spin numbers look a bit low. These are a couple of years old, but here are average tour trackman numbers through the bag. Granted they will be hitting the ball harder than you therefore more spin, but I don't think it should be that big a difference. Could be that you're not hitting down as much as you could be?

Agree with above. Spin rates are far too low for some reason, which is strange, seeing as GC2 directly measures it. Rough rule is that spin rate should 1000x the club you hit.

would take a can of foot spray to the range & check what's happening with contact on the vertical & horizontal axis over 6 shots with a variety of clubs.

sounds (assuming the gc2 set up ok & the ball position you're hitting from is ok - no real reason that this all wouldn't be ok as a rule) as if it's maybes an AoA & contact issue maybes on the vertical axis.

you wouldn't as a norm get the low end of the spin rate numbers you appear to be getting with such large roll outs, plus the little ways unusual gaping carry wise.

had the lofts checked through the set? if they are off any it would contribute but think it's probably down to something with the delivery of the clubhead.

when you out on course what's the height, curvature, starting direction of the ball relative to target?

First thanks for the input to everyone. I'm with you all on the run out, I'm taking all the figures with a pinch of salt.

Coach, I don't hit a high ball. I tend to draw the ball 90% of the time unless am trying to cut one deliberately but those attempts normally just go straight. (Unlike they do at the range) I do get decent run out (weather conditions defendant obviously) with the lower clubs however my wedges don't roll at all, they either stop or have been known to crawl back a bit from time to time, again a lot probably due to the course conditions.

I also agree that if anything I should get the lofts checked out. I've had the same clubs now for about 4 years and never had them checked. I did Snap the 6 iron round a tree once (not in anger) and had to get it re-shafted so perhaps there is a reason in there somewhere as to why the figures don't quite make sense.

if when you out in play, none of it is giving you any real issues, then wouldn't really trouble over it over much.
worth getting the loft checked on the irons maybes it's factoring in a tad on the gaping.

flight low-ish, flight left to right has you coming in from the inside so towards the shallow end of the spectrum. if not crazy in from the inside relative to the 0º target line again maybes something not to trouble over. (if you get on the LM again anytime worth paying attention to swing path into the ball in degress plus the AoA)

worth though spending a few bucks on a can on footspray to check out the strike on the vertical axis. if you were coming in too much from the inside so too shallow could put the strike too low out of the face. so in effect you could be hitting balls a little ways 'thin' so getting a bit of a flier type flight.

if that indeed did turn out to be an issue then from the top thinking you swing down a ways more in front of your chest & turning/rotating through exiting leftways after impact.

so kinda thinking more swing down in front of you then more round the corner left after impact.
which would bring you in a little ways steeper by neutralizing the swing path some bringing path back towards the 0º ball/target line which would also give you the chance of strike being higher on the face (vertical axis) so getting a bunch more spin so little higher flight. but as said depends if it's an issue when you play.

Cheers, I think I will get the lofts checked out the next time I am over there (have 2 more sessions to go)

I'll have a look at my swing, maybe even try get a video of it, I guess that factored in with 5 sessions on the GC2 should give and idea of where its all at.

If those are the averages were the bad shots removed to group each club distance better? That would cause the inaccuracies of the 6 and 7 iron distances.

Only look at carry figures, how do they compare to actual play for you?
