Have to disagree with you on fuel burn for touch and goes compared to cruise. I've just not seen that to be the case.

Michael,
Sorry, that is not correct.
The max payload is 490 pounds.
usable fuel, drain-able oil, luggage, and the humans are all part of that payload.
The fuel load, ~144 pounds for 24 gallons, leaves 346 pounds.
assuming the oil in the engine is 8pounds, leaves 338 pounds.
Just about enough for 2 FAA standard' weight persons.
Well, most American men weight are well above that 'FAA standard'.
The documentation does say that as much as 50 pounds can be put in the
storage//luggage compartment.
But we cannot afford the extra weight.
So, lets say the instructor weights 200 pounds.
that leaves 146 pounds for the student.
(assuming they can both crowd into the cockpit, it would be a real cosy fit.)
Hummmm......
I guess a cute little lady could qualify as the student without overloading the
plane.
There seems to be only one possible conclusion:
the skycatcher is engineered to make flying more accessible for the female
population.
The documentation I read did not mention the seat load limit, but the ASTM
required min value is 225pounds.
If my 300pounds were to be training in the skycatcher and the seat did not
collapse, the instructor would have to stay on the ground.
the documentation says a full tank will last a bit less than 4 hours.
If the fuel has to be reduced to accommodate the pilot/instructor, say by half,
then training time will be ~1.5 hours+plus reserve.
Touch-n-go practice will eat the fuel at a much higher rate than cruise
consumption of 6gal./hr.
I agree with Helen,
Training plane for solo training.
