There was a detailed explanation of spin loft in this video which I’ve cut out as I mangled the explanation a little. I’ll do another video on that soon ❤
I thought spin loft was the difference in dynamic loft and attack angle. So a dynamic loft of 50 degrees with an attack angle of -10 degrees would have a spin loft of 60 degrees. If the attack angle was steeper with -20 degrees the spin loft would be higher with 70 degrees not less with 30 degrees.
Exactly what i thought. Was going to make this comment and thought I'd just check my facts first and sure enough it's dynamic loft MINUS attack angle. (So with a descending blow you are minusing a negative number and hence are increasing the spin loft the more steeply descending the angle of attack eg 50(dynamic), minus -10(attack angle) = 60(spin loft). A steeper angle of attack thus increases spin loft ie 50(dyn) minus -12(attack ang) = 62(spin loft) An example of driver with a slight ascending blow would mean minusing a positive number and hence be reducing the dynamic loft number eg 13 minus +3 = 10. An even more ascending blow reduces spin loft eg 13 minus +5 = 8. A less ascending blow sees spin decrease, ie 13 minus +1 = 12. A descending blow with driver, with same dynamic loft, increases backspin ie 13 minus -3 = 16. With wedges i think maybe it's hard to hit more down without pushing hands forward at impact, hence you trade off dynamic loft for spin loft and gain no more spin. With driver reducing spin loft reduces backspin and increases distance up to a point, but then, depending on player's personal clubhead speed, less spin loft means so little backspin that the ball falls out of the air much sooner and you end up with less distance overall. So obviously it's about finding the optimal combinations of static loft, dynamic loft, angle of attack, and clubhead speed for each individual. Edit: Also I remember seeing a trackman video that talked about there coming a point with wedges where increased dynamic loft doesn't translate to more spin because you are delivering an increasingly glancing blow and you thus start to lose friction of ball on club face. This decrease in how much the clubface 'grips' the ball means that after a point increased dynamic loft actually sees spin reduce.
@davet2625 Bro... Thank you. I finally feel like I understand spin loft. Your explanation was so thorough and comprehensive. Correct me if I'm wrong, but my takeaway is that a steeper angle of descent increases spin, relative to the loft presented at impact remaining constant. The point at which the steeper angle leads to a decrease in loft at impact, the spin is no longer increased. Brilliant 👏
Doesn't the ability to spin the ball have a lot to do with also the surface you're hitting off of? (not just brought vs fairway but quality of the fairway itself)
Great video Pete, so simple to follow and great to hear the theory
Thanks Pete! Been struggling with this and flighting the wedges in a lower, more reasonable, window 👍🏻
This explanation was the best ever. Thank you Peter 🙏🏻 Awesome 🤘🏻😎🤘🏻
Great vid! best loft explanation i have seen actually understand it now 😅
Thank you 🙏
Wow, such detail. Its really appreciated. X
Thank you for watching

Thank you great video 😊
Need this 😂

Both things are true, it's Peters maths that causes confusion. 50 minus -10 = 60
Yeah I mangled the explanation a bit. I was trying to get across the angle of the face being moved by aoa, I’m trimming it from the video now

Huge benefit to "see" the workings and intent .... Now to actually apply it correctly! : ) Be Safe

Basically anything which has a chance to get in between the club and face. Longer grass, dirt, etc
Joe Mayo has been trying to explain that for 15 year to no avail…. Nice job! Maybe he just needed to lay down on his belly….😂😂
Off a mat, no thanks.
