If you are 20 ft up a tree and your target is 20 yds away - the difference between the base of tree measurement and stand measurement is " 1 yard" .

It doesn' t make a hill of beans.

I always range from the stand - any slight extra length is cancelled out by the arrows change from perpendicular to gravity. It travels a bit longer - but it drops a bit less because of this angle.

Just bend at the waist, practice from that height - and range from wherever you feel like it
