Snap Release is defined as a Release that's triggered at the end of a <Line> Delivery Path. So it concerns where it's Released -- and it's not a specific point/location -- because the end of the Delivery can be thought of as an area with boundaries.

If you want to use Max Trigger Delay in a Snap Release (or a Random Sweep Release, but not a Full Sweep Release), you must be using an Automatic Release. Because if it's Non-Automatic, you're thinking about manually triggering the release, and hence you will not be releasing as late as you can be, i.e. not Max Trigger Delay.
What would this look like? You would see the location of release delayed until the very end of the end of Delivery Path area.

So if you want to use Min Trigger Delay in a Snap Release, you will need a Non-Automatic Release. What would this look like? You would see the location of release delayed until the beginning of the end of Delivery Path area. But it's still within the end of Delivery Path area which defines the Snap Release.
[Above <Line> by Yoda. Circle Path permits no Snap Release.]

And there you have it.

Is the Angled Line Delivery Path the red-headed step child here or what?

Don't let this post "die off like the rest"...

Please continue discussing this wonderful post ....

Crack..Crack..Crack ...He's gonna hatch soon!!!

Also lets cover All the delivery paths, delivery lines, triggers, releases and their relationships to one another....

And Master Yoda...stay right here...Don't go back into meditation mode Stay with us on this!!!

Release And Trigger Delay On The Angled Line Delivery Path

My post above (Trigger Happy) applies to both the Straight Line and Angled Line Delivery Paths. Angled Line is the necessary Variation for those Plane Angles requiring a return to the Elbow Plane for Release, e.g., the Double Shift.

Oh, and don't worry, Annikan...

I'm not going anywhere!

I'm Lovin' It (McDonalds)
What a bubbly atmostphere! Absolutely fantastic! Lets make this "Release for Dummies" thread, "Thread of the Month" (I just made that up).

==============================================

Now, Mike O said he has a pretty simple answer to my question about Snap Release / Trigger Delay, but was going to keep quiet to see how things pan out. I wonder if his response is the same as Yoda's. Will the real Mike O please stand up

==============================================

In fact Mike and I has had some very interesting (probably more interesting to me than him since he knows pretty much everything already) discussions relating to Release via PMs. How selfish of me for not sharing this to the public.

Lets do this bit by bit. Starting from no particular place, lets look at 6-F-0 where Homer says "the Clubhead is not picking up speed during the Overtaking (Release) Interval, either when Hitting or Swinging".

Now we seem to have a direct contradiction in 8-9, where Homer says, "Release - ...the period of Clubhead Acceleration".

How can we reconcile the above?

I'll be back.

I'm pretty sure the statement from 6-F-0 is referring to Angular Speed -- i.e., RPM's. So, the clubhead is accelrating to keep up with the Angular Speed (RPM's) of the Primary Lever System. See 2-P where Mr. Kelley writes:
Spot on . If only Homer added the word 'Angular' in front of Speed, it would've saved me a few brain cells!

Here's a bit of trivia for you guys. In the Endless Belt Effect model shown in 2-K#6, is Clubhead Speed increasing (i.e. accelerating) during the curved portion of the belt as it goes round the pulley (labelled as Radial Travel on diagram)?

Their is a huge difference between Arc Velocity,Arc Acceleration, Angular Velocity and Angular Acceleration....So I don't think Homer was contridicting himself...

Remember Acceleration is a CHANGE in Distance divided by a CHANGE In Time....

Arc Velocity which is the measure of the Circumference of the Arc from one point to another...usually measured in radians or degrees of travel..

Arc Acceleration is alpha times the radiusmeasured in radians or degrees

Angular Velocity(omega x's the radius) is the measure of Angular Velocity around the Center usually measured in radians per second

Angular Acceleration is (alpha= final omega - initial omega divided by time) I believe measured in radians per second squared.


I didn't have my Biomechanics text in front of me...If there is an error in the formulas or units I will edit in the morning when I get to the University.

The chick is gonna hatch soon..Yoda keep the light on!!!!

Keep us warm....

Thanks Annikan

Velocity
Velocity= Distance divided by Time
Acceleration= Distance divided by Time squared

Endless Belt... imagine ducks going around on a shooting gallery. When the duck turns the corner... Zip, there he goes.

Another Peck at the Eggshell
The more delayed the release, the smaller the pulley, the faster the right elbow has to straighten. Right forearm paddlewheel motion (swingers), action (hitters).
