Sorry to hear about your misfortune, losing a deer is something that happens to just about everyone sooner or later. It sounds like you would probably NOT recovered this deer by getting down or staying put. You saw what direction he went and found blood twice, and still lost his trail. It sounds like a survivable shot, so if you got right down he would have bolted for the next county! If you stayed put, he would have eased off, and you'd still never see him again. But, I would have to agree with MZS, if he is not dead in sight, barring rain or over-crowded hunting grounds, staying put is the best choice!
