I found in my travels that not everything is per manual; manual is to get you there so to speak and the rest depends on many factors, such as elevation, temp, fuel, part quality, load, workmanship, luck, etc…certain final adjustments are made in respect to those factors. My two cents

It can be a life lesson journey, that's for sure! lol
