LOL-Welcome to hard, hag. By the looks of it you're starting out quite normally as a relatively new master. If you haven't figured it out yet the default green speed is now very fast. Heh-you'll figure it out and then when you do and go back to playing pro speeds you'll be venting all over again. It's fun!
For what it's worth when fast greens were introduced last year the difference was an increase of about 33%. A 6 foot stroke became 8 feet, or so. There are a lot of different tips on compensating for the different speeds and you can find them in the search box. GL
