I don't think this has anything to do with setting to an aggressive target decay (which by all means I agree with you). As soon as you get into the range where MRC actively starts creating filters it will run out of filters pretty quickly when the limit is 7. It starts allocating many filters long before it starts setting them to agressive.

If you think listening to music is fun, try learning an instrument.
