Now, if you want a compensating effect, you need to make sure the time between agitations is long enough. It would seem to me that this time would be longer with a more active developer than with a less active/weaker one. Therefore, to achieve a certain amount of compensation, one would have to increase the agitation intervals for the more active developer, not decrease them as the OP is suggesting.
Similarly, for weaker developers, the interval at which a certain amount of compensation occurs will be shorter. Therefore, for a given amount of compensation, one would have to increase the frequency of agitation compared to a more active developer, not decrease it.
Of course if you don't want and compensation, then just agitate away, it shouldn't make much difference at all as long as the agitations aren't long enough for developer to exhaust in the highlights; any agitation scheme that accomplishes this would yield the same results as long as development time was appropriately adjusted.
