If I remember right your old personal best was a 12.7x. If that's right a 0.2 drop without working on the short end is fantastic. You'll pick up another 0.2 getting the first 60' and 200 feet down. You are already cutting a better 60' than I am, so your setup seems to be working better to get around the throttle position issue.
