If your engine is already broke in (and your HSN is in the ballpark), then I would:
-Richen up both needles just enough that you are on the rich side
-Set idle gap
-Tune LSN until it's near ideal idle, bottom end is clearing out okay, and it drops back to idle smoothly - you may have to retune idle during this
-Hit track and get the engine back up to full temps with HSN on rich side still
-Tune HSN, run some more - lean it until the engine is hitting full RPM's and 'clearing out' without hesitation (listen carefully; going beyond this just leans the engine and brings up temps - there's no need to run overly lean for regular club racing); I also use smoke as an indicator, but different fuels have different oils/percentages, so if you tune with smoke, know your fuel!
-Bring back into pits after driving some laps and verify LSN/idle doesn't need touched again - this is where I'd also do the 10-15 second test on LSN
-I temp throughout the process just to confirm what I'm hearing/seeing/doing
