Looking at her spreadsheet I would got the other way...I would take her back to 3.25u, when she was on that dose back in Dec. she was getting mostly blues and greens, it just doesn't look like you held it long enough to let all her bouncing to stop and let her settle into the dose. She looks like one of those cats that might take a couple of weeks to settle down when she starts hitting even yellows and blues, just because her body has gotten so use to being high.
