been having some conversations with people lately and this topic has come up a lot.
98% of disc golfers have slip on nearly all of their drives (except for on grip locks).
people that max out ~400' still throw this way, with lots of slip.
this is very difficult to convey the concept, so i will list a ton of comparisons to try to help people make sense of it.
in baseball (and golf), there are hitters that SLAP the ball and hitters that DRIVE the ball. a hit that is "slapped" is where the ball bounces off of the bat (or club) after contact. these generally don't have home run power.
a hit that is "driven" is where the bat makes contact with the ball and then the hitter releases his wrists, causing a huge acceleration of the bat (or club) head and the bat head will fling the ball off the bat.
basically, a slap has very little force imparted on it. the bat redirects the ball.
a drive has high levels of force imparted on it. the bat stops the ball and then pushes the ball. this is the same for golf.
other sport motions that are applicable for comparison.
a hockey wrist shot is always a drive.
a hockey slap shot when executed well is a drive but when mis-timed it is a slap.
a novice at ping pong hits with a slap while that chinese guy on espn9 hits with a drive.
shuffleboard is always a drive.
a boxer who hits with a fully extended arm is a slap, a boxer who hits with a bent arm and extends his arm through the punch is a drive.
jai alai is always a drive.
a soccer kick can be either a slap or a drive.
the visual differences between a slap or a drive (minus seeing the result) is minute but if you train yourself to look for it it will become easy to see the differences. a drive will accelerate immediately after the point of contact. a slap will decelerate immediately after the point of contact.
there are technically 2 points of contact in a disc golf throw, but if you miss the first one (as most do), worrying about the second one is a waste of time, so i will focus on the initial point of contact.
the point of contact in a disc golf throw occurs when the disc enters the power zone, which is basically when the disc reaches the right edge of the body. the disc should be close to the body. the wrist is usually curled and the elbow is at its maximum amount of bend here.
this is the point of contact. the arm/disc must accelerate immediately after the point of contact.
the release of the bat head is the tug that follows, uncoiling the elbow and launching the disc. this is how you drive a disc (aka throw with snap).
at least 98% of players peak speed before the point of contact and decelerate out. the result is that the disc slips out on pretty much every throw but they have practiced their timing and positions allowing a slipped throw to come out straight.
this is why you see some guys who peak at 380' straight but can grip lock 450'. when they grip locked it they actually hit it.
this is how i derived the right pec drill... which is basically practicing throws starting just before the point of contact.
Added via edit: The only time when arm speed is of any importance is AFTER the point of contact.
