@Double7s... I too log every set I ski! I started on myskilog.com a few years ago and now in my own journal... It is kind of fun to see where you are each year and what the conditions were/are (weather temp, water temp, wind, boats, lakes, drivers, settings, bindings, ski's, time of day, which set in the day, what you were working on, tips that worked and those that didn't...etc) ... I know that is a lot to think of and believe me I do NOT think of these on each of my sets... But we all enoy this sport so much and we want to get better that some of us do this...
I enjoy comparing where I am at now, and just this year I am keeping a personal PB list just for this year and not 1, 2 or 3 years back... I think that is making it that much more fun and I still look forward to those little PB's 1/2 buoy at a time:-)
