Your example rocket made an unnecessary orbit. You went from LEO to
transfer orbit, let it come back to intersect with LEO again and
back to GEO intersect a second time when you finally fired the
rockets to maintain GEO. You could have fired them after half a
transer-orbit instead of one-and-a-half and gotten the job done
quicker and not had to pay your staff overtime.
I fully agree. The reason I waited to fire the apogee kick motor
was to illustrate the orbital mechanics: without further action,
the satellite will arrive back at the low-altitude, high-speed perigee.
