You can do both mini bumps and super bumps -- they don't interfere with each other. If you try to ration your super bumps, then you're just throwing some of that potential effect away.
Hmmm... equally spacing out super bumps over the course of the month seems to result in a lower total bumping effect than e.g. sending a bunch of superbumps in one day, waiting 30 days and 1 minute, and doing it again.
