That is a legitimate hit and the beginner framing makes it worse, agreed. A floor shown to someone who does not know it is a floor gets read as a budget, and then they buy the 1 GB box.

Two things I am changing. First, I am measuring peak RSS under concurrent load now so no app is ever listed with only an idle figure. Second, the site framing goes, because “here is the floor, good luck” is exactly the rest-of-the-owl problem you are describing.

If you have a multiplier you actually trust for the gap between idle and real usage, I would rather publish yours with credit than invent one.
