Who really cares about the science behind throw angle?
A better term than throw would be spin/speed ratio or tangential COR/normal COR ratio. This factors out the swing of the human and makes it easier to rate the rubbers alone and not the rubber+players.
I would be stupid to say that what you guys call throw angle doesn't exist but the rest of the forum has doesn't have a definition for throw angle and often people use the term long throw, high throw or just throw.UpSideDownCarl said:Why is this interesting? He has actually admitted that there is such a thing as throw angle.
Yes, I will avoid the term because throw angle is dependent on the stroke too and therefore not a good way to judge a rubber or blade. Spin/speed ratio is much better. Better yet tangential COR/normal COR.Even though it is clear he is avoiding using the term. So a term he has said doesn't exist, he has just defined. In my book that is interesting.
No, dwell time has little to do with throw angle. Dwell time is more a function of impact speed and distance to stop the ball relative to the blade. Brushing strokes will have a little more dwell time but not much more. You guys have to remember I have the high speed videos.With a blade throw angle might be dwell time/speed ratio.
High loops bounce high. They are too easy to counter hit.I personally like high throw angle blades and rubbers. And unlike Pnatchtwey, I often aim way higher than 4 inches above the net. High spinny loops that land right on the base line off a heavy chop are good stuff.
They will still bounce high. If they have lots of spin the magnus effect may keep the bounce a little lower but that requires a lot of spin.But often my power loops have enough spin so that, if they are a foot from the end of the table and two feet above the table, they will still get pulled down by the spin and land.

Actually, the spin can't be seen. There are no marks on the ball and the camera frames aren't fast enough to show the spin. The frame rate would have to be at more than twice spin rate to capture spin. Also, notice that the shutter speed is too long. Long shutter speeds make it easy to take videos in normal light but the ball looks like a blur.Here is a good example how the speed/spin can be visualized ,... from time 07:00
What are the advantages and disadvantages of high and low throw rubbers?

I have defined throw angle as atan2(vertical_speed_after_impact/horizontal_speed_after_impact).

Der-Echte can FRISBY BH throw a rubber pretty darned low and far.
Does that count for anything?
