This is from the original thread: "I don't go backwards though (i.e. back to paper or walk-back after BH tuning). I make sure my BH and FP's are grouping and then I check at another yardage (at least 15 yards greater) and figure I am good-to-go"

OH, don't get me wrong b/c I'm not slamming Doc, he's probably forgotten more than I'll know, but I believe people are using this method out of context. People THINK there bow is in specs then go adjusting this and that and get the POI the same and think there bow is tuned and it's not. Sure the POI is the same, but all that means is that both the broadhead tipped arrows and fieldpoints are fishtailing their way to the same spot. Of course it's a valid method, but only if it's used with other methods.
