If you can handle the math. Bill Patterson did all the work, years ago. His work is spot on.

Windy, but the BMC powers through it well. Makes about 20-24 mph up on the level and moderate uphills.
The bike doesn't feel totally stable to me, but it goes where I want it to.

I read that a good rider on a recumbent beat four probably better riders in a peleton. So perhaps a recumbent is comparable to the efficiency of a peleton.

On the downhills at low speed the EbikeE would go faster than the Tapole. At higher speeds the Tadpole would glide away from the EbikeE, so we could see rolling resistance (and cogging) vs air resistance in action.
At the end of the trip the watt hours per mile were about 15 for the EbikeE and Tadpole, and 25-30 for the BMX and Borg. Not a precise A-B comparison, but interesting nonetheless.
We also traded bikes a bit and Stevil, acuteaero and I got to experience the three uprights. Quite a difference and range of riding comfort and position. The BMX is small and harsh, even with the Thudbuster it is noticeable. A softer seat may help. The small wheels and short wheelbase is likely part of the cause.
