The best way to know is get in your tree stand with your hunting clothes in and the broadheads you will use and see where YOU hit...
There is much that can go wrong when 20 feet up in a tree trying to shoot down at a deer...
Trust me...I know...
Why spend all the time/money on this sport and not know what will happen...
I've seen anchor points move from the mesh camo worn...Hat brims that interfere with the string...Peeps that don't line up like they should...Harnesses that don't bend with the hunter...Limbs hit the side of the stand...Rests that don't cut it when bending down...
Any of these can spoil a hunt...
