Any information? Sure.....it set up my next question. I had to make sure I was thinking correctly on THAT one beofre I made any assumptions on the next one. So yeah....I learned something. It's not picking nits.....it either "is" or it "isn't". No grey area. Couldn't move "each" the same.....even on the same bow/setup. Never eluded to that.....and admitted my sketch was not to scale.
OK.....so that being what "is"......
What happens on the straight down shot?.....since gravity becomes a non-factor?
I may have just proved MYSELF wrong in a previous post......which was what I was after.
Assuming the shooter/hunter was 20yds up in the tree (for this exercise).......it would seem the lines would NOT meet back at 20yds (even though they WOULD still meet at 'per Matt/PA' 8yds)......and the shooter would shoot HIGH if he utilized his 20yd pin.
Is THIS incorrect/correct logic?
Jeff, your sketch is correct. Did it provide any information to you? To me, I see that if you move the target up/down, and/or the bow up/down, the arrow CANNOT be parallel to the ground any more as indicated in your sketch. (I better list my obvious assumption since you seem very interested in picking nits today: you dont move 'each' the same distance one direction)

The arrow is no longer traveling perpendicular to gravity, the the affect is lessed...

I haven't shot this shot in a couple years, now.....and it's clear I didn't understand it whenI was shooting it (for practice, only). I'm really trying to learn something with all this.....if you'll bear with me.

Jeff, here a is a pic of trajectory, note, the different angles are angles of launch. I.E. the angle the arrow is relative to horizontal when it leaves the bow.

RE: Compound bow - set up question
So technically if you could shoot "straight" down, the flight of your arrow would no longer be a parabolic curve, and would once again be very nearly a straight line. Your sights would be setup to compensate for the curve of the mystical flight of the arrow, which would no longer exist... Now the arrows path IS a straight line (which we said didn't happen, my my crow tastes good
). Now you should shoot high because your sights are compensating for dro that isn't there.

I have never taken the shot tho would be interesting to find somewhere to practice 20 yards straid down.
