Hmmm, interesting question. You are absolutely right that what they are recommending seems way too low for you.
I would think that they use the same formula as for weight-loss (www.sparkpeople.com/resource/calorie_calcu
), but skip the "Step 7" where they deduct for the calorie deficit.
So, it would be BMR x 1.2 + exercise calories to get the centre of the range.
Have you checked to see what is recommended for maintenance on other sites?
Edit: Excuse the last line - I see now that you state right in your OP that you have! I really do have a dumb today...Sorry!
I did a quick check on another calculator that I know of, and they show maintenance for you at 1844 per day (which would be around 1600-1950 by the Spark ranges).
