> Going from 310 to 700km in a year is not doing us anything.

Im not following this closely, but that statement misses the most
important reason for doing this...


The lifetime of a cubesat at 310km is only a few weeks at most.  The life
time at 700km is tens of years.

The minimum requirement then for an ION thruster, then, is to be able to
at least be slightly greater than the loss on every orbit.  Then it is
worth its weight in gold!
