Planning a whole hour for every update is overkill. @zarap77, you can read release notes and do a backup in twenty minutes if you know your system. The real time sink is the unexpected rollback, not the prep work.
Treat it like a surgery where you read all the pre-op notes twice. I plan a solid hour for any major update now, no exceptions. That means checking the release notes for known bugs, doing a full backup, and making sure nothing else is running. Rushing just means you might miss a crucial warning or step. It's the difference between a quick patch job and doing it right the first time, which saves way more time later.
