NEWBY ALERT!!
I love analogies, helps me understand complicated things.
I would not want to pull a semi load od canned goods with a corvette. For that I want  K-whopper of Mack.

Yes the 'vette is faster, but it won't handle the heavier lo
ad as well.
 Is there any relationship in this to cast and speed, assuming we are dealing with heavier/lighter arrows?

Hill style bows have more cast than any other bow.  That is they can cast a spell on you from further away than any other bow.

right on. .   I think the point is, what ever speed is given to the arrow is given while the arrow is on the string.  Once it is off, it is on its own.
. . That doesn't change anything here.  Two
Some bows are alleged to throw heavier arrows more efficiently than others and vice versa.  Whateveridentical arrows going the same speed and with the same flight (tuned etc, had to throw that in) will go generally the same distance.

I agree, cast was the word used in "the day" because that was the only real way to measure the bows performance.  Now we generally (but not always) cite speed.

Again it begs the question. .  so what ?  My bow performs as it does.  I am not likely going to trade it off for another to gain 5 feet of "cast".  At 20 yards, no critter will care about my bow's cast or speed.

Pavan. .  I think you may be correct there !

So. .  extend this wonderful discussion.  How many angels could dance on the head of an arrow (assuming a 175 grain head) while it is being cast into the north wind ?

While you all try to figure this out I'm going to go shoot my unchronographed bow

I think you would be talking horsepower  vs. torque.  I don't thing that would be a fair  comparison to cast vs. speed.  Maybe more like horsepower vs. mpg!!

Exactly, Back in the time before we had Chronographs the only real way we had to check a bows performance was to take two bows of exactly the same poundage and shoot the same arrow out of it. We had to do that several times because we had to rely on the shooter pulling the same distance and same angle. We would put a piece of tape or mark on the arrow to make sure we pulled it the same distance and we would watch the shooter to try to get the same angle.
The bow that (CAST) the arrow the farthest was the bow with more cast ( actually put more of its power into the arrow flight).
We can now easily judge that by testing with machines and chronographs and much more accurately determine the bow efficiency.
