I've allways known that it should be possible. Never tried if it works
WELL, which is an entierly different matter.

Actually, it is not even the reversed log you are after, it just
"fits" what you are out for.

In the end, experience will tell if it works well for the application
at hand, a filter Q value in this case.

The trick of loading a pot (as seen above for instance) is also of
nice help. Maybe some day I make a bunch of simulations and put up,
until then, test the hell out and see what works and report back ;O)

Cheers,
