Here's the full length of the 3-6-9 putting drill, if you're interested in masochism, and wanted to see how long it actually took (edited for entertainment's sake, because missing putts over and over again gets boring, unless you're Jordan Spieth, I guess). How many attempts does it take to complete the drill!? I lost count, but definitely tracked the time. Many thanks to Corpus Christi Country Club for their outstanding practice facility.
Not eager to watch 18 mins of putts and gradual improvement? Skip to 16:01 for spoilers :D
