Maf Rescale issues in HP Tuners

I seem to be having an issue getting my Maf dialed in as accurately as I'd like. After making a maf error histogram in hp scanner and then copy and pasting it into the editor, it seems like the new tune always goes way too far one way or the other and I'm constantly fighting this battle of over correction. I'm using paste special multiply by percent-half when I do this.

For some context I have all the fuel trims disabled and my EQ targets set to 1.00 lambda across the board to assure that's what's always being commanded. I'm following a pretty straight forward process however for example if during one run I have several cells that are up to 4% lean, after doing the multiply by percent half method the next run will end up with those same cells up to 4% rich sometimes with seemingly no rhyme or reason. It makes getting my fuel trims even close to 2-3% a nightmare.

Has anybody else out there ever experienced anything like this using HP Tuners? I had similar headaches tuning the VVE table. If anybody knows what causes this or how to fix it I would appreciate it so so much. This back and fourth game is driving me crazy lol

What filters (if any) are you applying to your MAF error table in VCM Scanner?
