Exactly. Running a tad lean (lean being a relative term here) during light cruise (minimum load) is not uncommon for most auto manufacturers. In fact, I've seen as high as 15.8:1 under light cruise. Under acceleration or load, fuel curves will richen up as necessary to keep things safe.

Bring back  Windows™ XP and 7. 
Windows™ Vista and Windows™ 8 is a pain in my a$$! 
Windows™ 10 is only slightly less annoying! 
Windows™ 11 is garbage! 
Much to my surprise, I'm actually quite enjoying Linux!
