It really depends on the length and difficulty of the course and type of course. My guesses are, for a typical PGA tour course playing around 69-7100 yds, I would say 270 for drives (about Fred Funk length) and 185 to 190 for a five iron. For the seniors, averaging around 65-6600 yds, probably about 260 minimum and 180-185 five iron, for the LPGA averaging around 63-6400, around 250 drive and 175 to 180 five iron. My guess is the average publice golf course on a weekend is set up to about 63-6400 yds from the white tees and 65-6600 yds from the back tees.
