well how disappoint you should get should also depends on your weight. If you're anything under 150 lbs, that's a decent start, and if you're under 140 lbs, that's a great start, and if under 130 lbs, that's cat3 potential down the road right there!I wish I had even your starting numbers. I just got a Stages PM, and did a FTP test. 191.
While disappointing, these numbers will be useful on and off the trainer. This gives me a consistent base to start from. My goal is to hit 250 by April (maybe unrealistic, but it's a goal).
