Fletch,

In my experience, anyone I have seen that has the expertise to do the fiddling with Storable that you are indicating has the expertise to do handle the compression handicapping. In fact, the skill level is such that I would expect that they would in fact know what they were doing if they were tweaking the config in the first place - which gets me back to the point I made previously - I don't think we are hearing the whole story. But again, *shrug*, I doesn't really matter to me.
