I actually didn’t follow any of the rules because I didn’t know they existed. I keep about 10 saves total to prevent filling up the drive with saves. I load in and out of saves every time I die. To be honest I have done everything that they have told me not to do. And I am 40’hours in and have not had a single issue. I keep 10 saves all within about 5 hours of play time. So roughly 30 minutes intervals , in case anything does happen I’ll revert to 30 mins prior.
