Exactly as I thought mattio, for as long as I could remember. I've been searching for systems for decades and having a link between the filters seems to be the way to go, and it is too (yup a cointradiction), BUT I have 6 filters (one is price ..... whoopee $4.00 to $30.00 - big deal eh ?) and the others can be used on any system and improve the POT - which you believe will cause more harm than good - fair enough too. I would have argued till I was blue in the face about the same thing, BUT I now believe it's wrong.

I pump in some logical filters and continue to test each of these 6 filters, and it keeps improving the POT, or reducing a LOT.

The one name I couldn't remember last night was punter57, who hosted the longshot system. There's a wealth of information in there including a few standout arguments for and reasoning for going against what nearly all punters have as "non-negotiables".

Go against the "non-negotiables", and all things being equal (ie; they all have four legs), your POT has to improve, coz' no one has their money parked there !!!!
