Another important aspect I forgot is.....

How good are you at estimating ranges? Do you shoot 3-d shoots? They are great practice at estimation. You can be super accurate at home but if you cant accurately know the distance to the deer in the stand it doesnt matter how well you shoot.

There are two ways around this though.
One.... mark trees at known ranges with ribbons or use a rangefinder.

Two....Set your bow with one pin for 24 yards and that will usually give you a good hit from 0 to 30 or so yards. Make sure to verify this on targets first though.
