I think it's simply the lack of frequent play, dyb. Play every day and you become familiar with the meter speed that goes with each club type in your bag - driver, woods, irons, wedges, and (most important of all) your putter.
With longer periods between game play, you are essentially having to 'relearn' the game each time you play.
Here's one suggestion: a CTTH game (closest to the hole) takes less than 5 minutes; commit yourself to playing AT LEAST 1 of those per day. That way you will maintain your 'meter sense' using a variety of club types.
All that said, even talented, steady, multiple rounds-per-day players will suffer through spells of poor play when it seems the golf gods have it in for you.
Oh, and Chris?
chrisironsbones: Or you might not be alone and WGT have tightened up the game for all of us..LOL
I know I'm not the only one who believes WGT has indeed 'tightened up the game' for all of us. Putting especially is more difficult the last 2 months or so.
