As a match director and course planner for 3 courses with mostly up and down hill lanes... some very steep up and down hill lanes... I'm wondering..

Let's say I'm setting a target on a 23 degree downhill lane.   I get my tape or range finder and say I like that tree at, what the range finder says, is 53 yards... I'll place it on the knot hole by that limb 4' off the ground.  Whether or not I also pull the tape measure and establish the accurate distance on that angle to the target... should I call it a 53 yard target on the course planner for the BOG, or do the math and figure the right angle or "gravity" distance?  Which could be called "Illegal" or "maybe proper"?  What would you do as a MD if ya were one or are one:-)

Better still...

 

What if I place a target on a 30 degree angle down hill at 57 yards by the tape measure?  Can a competitor call it an "illegal target"?

 

 I could say " no it's less than 55 by gravity or true distance".. or Maybe Scott could say:-)

IMHO what matters is the true distance from the shooting lane to the target, and this can not be over 55yds.

the further math that the shooter has to do is part of the fun.

JMHO, if you measure from the shooting line to face of target with a tape measure or range finder, anything over 55 yards is "illegal". Don

The target distance is from between the lane markers, at ground level, to the KZ. Regardless of incline/decline angle.

A 53 yard shot. 23 degrees decline. A very tall standing shooter (6' line of sight) will measure the target to be a little steeper (25 degrees) and a little longer (54 yards). That's on them to deal with.

"Better still...

What if I place a target on a 30 degree angle down hill at 57 yards by the tape measure? Can a competitor call it an "illegal target"? ..."

That would be an illegal target.

Edit: Say you had a 1" target at 40 yards. If you use the line of sight distance, the difficulty factor is 40T for a level target. If the target were straight up, the difficulty factor would be 50T.

40T vs 50T. Shot gets harder, difficulty factor goes up. That makes some sense.

If you used gravity distance, it would be 40T vs 0T. Shot gets harder, difficulty factor goes way down. That makes no sense.

Scott, I agree with your thinking.  The pellet does travel from the barrel to the target, so listing that as the range makes sense.  Where you aim or set your clicks on incline and decline targets is up to the shooter.
