If you did not see the arrow hit and there is no blood, you most likely missed. As far as not finding the arrow goes, I have had arrows miss the target and go into my lawn and I knew exactly where they hit, yet it took a while to find the arrow right in front of me - it is not hard to lose an arrow. 30 yds is a long shot (in my book) even if you have correct form. Contorting yourself like that would make for bad form. I find I am off if I even have to hunch down a little shooting from my ground blind cause the shooting window is too low.
