Can someone who knows about these things perhaps post a write up about what we should be looking for if we are hitting some balls using a launch monitor.

For example.
What is Smash? What's a good number for it?
Swing speed - Pretty self explanitory. But for example my driver speed is approx. 10-15 mpg faster than my irons. Is this standard?
Ball Speed - Again pretty self explanatory but how import is this number.
Spin - Again pretty self explanatory but again what kind of numbers should I be looking for?

Heck for all I know this isn't even a launch monitor. Some one help?

What is Smash? What's a good number for it?

1.5 is pretty much considered the maximum. Smash factor = ball speed / driver clubhead speed. It basically measures how good your contact is. Contact too low, high, or towards the heel or two results in a lower ball speed and thus a lower smash factor.

Swing speed - Pretty self explanitory. But for example my driver speed is approx. 10-15 mpg slower than my irons. Is this standard?

Slower? Your swing speed should get faster with the longer clubs. Your PW should be slower than your 5-iron and your driver clubhead speed should be fastest of all.

Ball Speed - Again pretty self explanatory but how import is this number.

Off the driver, very. Again, see smash factor.

Spin - Again pretty self explanatory but again what kind of numbers should I be looking for?

It depends on your launch angle and ball speed.

OOps sorry I meant to say faster. Thanks for the catch. I'll go back and edit.

the new PGA Tour Superstore here in Dallas has 12 launch monitors and they measure everything. I guess that smash factor and ball speed matter in that it calculates your efficiency on your shots. If you swing 110 with a driver, but ball speed is only 135, then you are very inefficient. I think I was around 105 and 145, which was a pretty decent combo for a 4 handicap. Most will also measure sidespin, offline distance and face angle which is very important.

With a driver, backspin is one of the keys to distance. Without getting too detailed, the spin starts about at about 2700/3000 rpm backspin. It slows as it goes, and that is affected mostly by time aloft. Time aloft of 7.0 - 7.3 seconds is awesome.

Some combination of rpm/speed produces optimal lift. The right rpm/forward speed combo at the high point of the drive's arc causes the ball to kind of hang there a short while, and that gives you an extra 20 or 30 yards if things are right. If the spin rate hits optimal too early the ball balloons, too late and you miss the advantage. Launch angle, backspin, speed .. all keys to the distance, and finding the right head/shaft/ball combo for your swing is why they have so many of last-years' drivers for sale cheap on e-bay.

      "5 Minutes Daily" Practice Challenge

      By Shindig · Posted

      Day 37, June 10.  Today was primarily WFH, so I had several practice sessions (indoors, off a mat, into the net).  At least one each of U, 9, and 6-iron full swings with the usual priority.   I also tried a few times a putting type stroke with my 4H, as something I should probably learn how to hit (and what it does), but the mechanical shot at home off a mat doesn't tell me much of what it's doing.  That's something I should probably try on a real green, not during a round until I've tried it.

      Day 10 (10 Jun 26) - Played in the midweek shootout at my home course - on aerated and sanded greens - day of trying to figure tempo to get the best roll on the greens.  Approach game was decently solid as was shots off the tee.

      My Swing (saevel25)

      By saevel25 · Posted

      Ok, I'm trying to find a feel to hit a consistent ball flight (irons).  My current predicament.  1. I try to do the arms down stuff better, with the club feeling like it is way behind me more. It's just a cluster of results. Most of the time, I can't get any speed on the swing. If I get my arms down faster, I just throw them out.  2. I focus all my attention on turning better. Pushing off with my left leg and getting my right side through better. On the DTL view, this doesn't produce anywhere close where the hands and club should be. The result is usually ball first contact, lower ball flight, more centered contact.  At this point, I am going with option 2. Stop thinking about what the hands do. Just make a shorter backswing, keep it wide, turn through. Somehow, the club head finds the ball. My focus is so much on just making sure I turn, it's like, "Oh, that contact was better.... Oh, that bell flight looks playable." If not, I will just be practicing my entire summer.

      Nope, they spent too much money. They are in over 28 million on the football roster and related NIL compensation at this point. Boosters associated with any Texas college football team has HUGE sway. The AD is between a rock and a hard place. They put a lot of money into Sorsby, at the chance of winning a NC this year. If you move on, you basically wasted a lot.  This is why Ohio State wants 3 QB's they feel can start. That is why the backups the past 5 years at some point transfer. Texas Tech has no backup near the quality of Sorsby. If they move on, they are screwed for 2026.

      Maybe there's something I still don't understand about the situation. Wouldn't Texas Tech do itself a favor to move on from Sorsby at this point?
