SaroorHai,
Your right it is right at 13yds, I screwed up the conversion!
So much for good math skills. Yikes!
I can tell you this that almost straight down angled shots are some of the most difficult to attempt. Going pretty high does change your shot perspective quite a bit, things are not what they sometimes seem. Practice from shooting heights is important like others have said above.
Chad,
The distance the deer is from the tree is 10yds, but the distance the arrow will travel is different and will vary depending upon your height. At 25ft is about 13yds as I stand corrected to.
