I thank you once again. The handbook does say in section 23.4.2 that if /usr/src/UPDATING contradicts something you read in the handbook, UPDATING takes precedence so I guess it does cover itself. The steps in UPDATING seem to work pretty well. I sometimes do mergemaster -iU at the second mergemaster step in the "To rebuild everything and install it on the current system" step as I mostly don't change the files that get reviewed by mergemaster, otherwise I stick exactly to UPDATING and get almost no problems.
