AS i understand it a larger tank is better because the pump runs longer
for
each cycle but cycles less, which is what causes pump problems.

That is correct. Usually the most problems will be caused by the motor
cycling off and on more. When a motor starts up it draws more current for a
short period of time while the motor is starting up. This puts more stress
on the motor. If you have a motor like on my well, there is a set of points
that puts a capacitor in and out of the circuit for about a second at
startup while the motor comes up to speed. The more often the points cycle,
the faster they wear out.
