I always lean during cruise. MP varies a lot due to density altitude, temp, people on board, fuel, etc., but normal cruise for me here (1200') is around 21". When I'm light on a cool day it can be down to 17-18". Real hot and heavy maybe 23-24". At 80-85mph cruise I usually get 12-13 gph. I haven't compared leaning vs. not doing ground work nor compared power available between the two.
