Just set it at 6k Andy and be done with it. You're cam's broke in, you're not seating rings or anything, and then see what she'll do!
(Had to revamp my mounting and wiring on mine after a near death experience for it, and reset it to 6k while I was at it, Mallory unit so just a couple dip switches, we'll see how she does Thursday, but really saw no speed increase riding it at 5k from the readings I got at 4200).
I think my rings should be well seated by now.
