Congratulations, and welcome.
1700 commuting miles in a year is a terrific accomplishment. It's 1700 miles more than almost everybody else in the US does, for one thing.
If you really want to compare yourself to ther riders, search some of the old threads. There a re a lot of polls that attack this topic from various perspectives ("How far...?" "How long...?" How often...?").
But nuts to that. Compare how you feel today to how you felt a year ago. That's what's important.
