i stick to my method

2 tanks idle
2 tanks extremely rich on flat surface aka streets in front of house
3-4 tanks with hour leaner still only going 1/4 throttle
2 tanks a little leaner half throttle(longer inputs before resting engine)
bring temps up from the 170 they are to about 200 or so leaving a little rich and run up to about 11 tanks that way then run all out lol..btw my track design is a LTO format just like an oval but much shorter of course

so far this has worked well for me
