Glad you found the deer, but I disagree on string jump and not taking slow walking shots at short distances. My thinking and experience:

At least 1/2 of my kills have been at slow walking deer, most at short distances. My longest shot at a slow walking deer was a double lung passthoughfrom 37 yds. at a 9 pt. buck. Dead run to 60 yds. and he piled up. I believe deer can string jump easier while standing still than they can while walking because of being more alert. A deer in an easy, slowstride is not as alert and cannot jumpor duck as quickly because he is in 1/2 stride(rather he is making strides), which will slow his reaction time slightly. JMO, but its always worked for me successfully.
