Only to add, Kevin Na was the first person in history (of record) to win a tour event with a negative strokes gained tee to green stat. It took him making over 550 ft of putts to do so. So, not only is it incredibly rare to play great golf with terrible ballstriking, it takes nearly perfect putting performance (like on those Tiger Woods PGA Tour games where your putting stat is maxed out and you use "Tiger Vision" to read those hard putts) to overcome your lack of ballstriking.
Doesn't this just change your waiting place from the tee to the fairway? Does it really save any time?
But yes I tee off as soon as the group in front is out of range. It gives me more time to look for my ball (doesn't save a stoke if it take more than 3 minutes, just a couple dollars).
