I was going on the common use of the phrase "the air is "soupy" due to humidity". but after doing some quick research it appears this is wrong - water vapor is less dense than dry air.

Is anybody else getting an ad for iTunes Gift Cards instead of the graphics in the original post?
max was 2300 RPM at 54mph, while 2000 RPM was 80mph.
A disc does not behave like a helicopter. The physics are different between a disc's monolithic wing and a helicopter's blades. The advancing vs retreating side of the disc do not create an imbalance in lift.
More spin is going to stabilize/maintain the disc's angle of release, so it would turn less. Throwing higher velocity with lower spin is going to turn the disc over more.Assuming RHBH looking at the disc flying away :
With 2300 at 54 mph (79 ft/sec) the right edge is actually moving backwards at 3.7 ft/sec and the left edge is going 162 ft/sec. Or just over twice the main velocity
With 2000 at 80 (117 ft/sec) the right edge is going 45.2 and the left edge is going 189 ft/sec. Or just 1.6 the forward velocity.
Unfortunately there's no indication of the flight path of these two conditions. Did the condition with the most left/right speed difference (2300@54) "turn" the most? Or does the spin not have an impact on HSS and just help stabilize the disc and resist the slow speed fade?
That's what I was starting to get from these descriptions but it seems that when I'm trying to turn an understable disc if I don't get enough spin it just goes straight and fades out.
Also does a person getting more "hit" generally have both more spin and velocity or just higher velocity than those of us that are maxing out at 300-325? It seems that since the hit comes from the final wrist motion it would be both.
You need to get the disc up to speed to turn.That's what I was starting to get from these descriptions but it seems that when I'm trying to turn an understable disc if I don't get enough spin it just goes straight and fades out.

Spin is a byproduct of throwing fast.
People who are throwing faster are generating more spin because they throw faster. It's not a separate characteristic; it's dependent. So yes. They are throwing faster and also generating more spin. However I think there is a point where you just can't control it anymore and what you get is what you get. Some throw with more and some with less spin as a result of that last part of the throw. Spin is a result of hanging on to the disc later into the swing...easier to do when throwing slow. So more potential if you are throwing fast, but easier to hang on if slow.
I'm no scientist and not very good at math but it seems to me that all that really matters in this equation would be the speed of the hand/wrist at release at maximum arm extension and how long the person can hold on to get an ideal release point.
So no, I don't really think throwing in different styles would give you different spin for a given armspeed at release. I think it all boils down to the grip and when the disc pulls out of your hand.
And I don't really think consciously trying to clamp down or curl a wrist, etc, to impart more spin is a feasible pursuit. Maybe on the touchiest of touch shots. Even then, meh.

But the wrist needs to be firm to transfer momentum.The wrist being loose allows the momentum created by the body to translate into snap.
The only logical conclusion I can come to is that only grip really effects the spin imparted to the disc for any given speed. all that matters is how much of a pinch you've got at the end and where that fulcrum is located. The style of the throw does not enter the equation. Less of a pinch force or inward on the disc=less spin. More of a pinch force or outward on the disc=more spin. However, I think we can all agree that you want to be gripping the disc close to the rim, not out on the flight plate, so I think the argument is impractical. And a loose grip+high launch speed equals early release, also undesirable. So really the question isn't can you consciously influence how much spin is imparted....It's a question of how to produce the most spin for any given throw. And that is simple. Create as fast a hand speed as possible and hang on as tight as you can.
