Similarly if you run a whole lot of systems for a while then stop 
most of them, your hours/day will be well in excess of the systems 
apparently allocated - but falling asymptotically to the true value 
as time goes on.

Not quite right.

The "mysterious" protocol is simply to allocate the smallest exponent 
available in each assignment type. If an assignment expires it is 
made available for reallocation in a daily job starting at 0600 UTC. 
If a user voluntarily returns an assignment it becomes available for 
reassignment immediately.

PrimeNet credits you with CPU time if you use the automatic method to 
report the result of an assignment but not if you use the manual 
assignment form. It doesn't matter whether you got the assignment 
using the automatic method or using the manual assignment form.
