I usually charge mine after each round. When I upload the round, I leave it plugged in a few extra minutes until it's charged. I always turn it off after the round. When I travel and don't have a chance to sync it right after a round, I've had mine last three rounds.
But now that tiger has done it and proven to himself and his competitors he is a world class threat again, the sky is the limit for him. He can win the US Open this year. Maybe even should win. I think Rory is going to complete the career slam, eventually. Maybe next year for all we know.
So.....that was a nicely thought out apparently....Let's see how the US Open/PGA comment plays out over the next couple years....
For the next round - I still think Rory will find his old game and get the C-slam, but as for even more majors for Tiger...now that he's playing like he should, Tiger gets 4 tries a year, Rory just the one.
I would flip this around.
Most tour-level players can't and shouldn't teach after they are no longer competitive. They have no knowledge or skill in teaching, nor any talent to teach, let alone teach golf.
But it's an incorrect and damaging one that should vanish from usage. I think we'd all agree that golf, and the world at large, can use more smart, dedicated, trained, and fairly compensated teachers.
