That thought occurred to me, too, about 3-4 times as much chain as an upright. I haven't kept good records of time and distance (yeah, I know I should) but a SWAG (scientific wild-assed guess) would be ~4000. (Medical issues have interfered on several years.) Your other point, that you can't drive the bike with your weight, is probably also significant. That's one thing I like about recumbents: whatever you do is your own muscles, not gravity (except going down-slope.) In cycling, we all know that whatever comes down must also go up.
