I think Mikelavigne said it perfectly (quoted below):
If I understand him correctly, he is doing the same thing I am. Setting the cartridge to the hundredths of a gram by ear and then being able to return to that EXACT weight of perfect performance after a change.
Sean, this may be the first time ever, you did NOT advocate using a tool or measuring device in order to perfect end results.
I can really be confident of a repeatable measurement. This is especially helpful if you own and use multiple cartridges. You are able to go back to your exact previous setup without the sometimes painstaking listening process of finding that sweet spot.
