Max Pressure Cold vs Hot Pressures - How Much Is Too Much

I agree... it is load limit, and if you exceed the load by a pound you should go to the next higher rating. BUT, my interpretation of Cummins 12v98's post is even if I were at or below the appropriate rating, he recommends adding 5 PSI. Just strikes me odd that he (and others) are so adamant about following the chart, but then decide on their own to only take it as a recommendation and create their own chart (in their mind).

Just an observation, nothing more.
