That works for me.Right. A good test of whether something is simulationistic is to see whether it makes sense for the people in the setting discuss about the things represented by the rules and would they make the same conclusions than the player that are looking at the rules.
Wizards certainly notice whether they gain all their spells back after a good night's sleep (even if it happens in the dungeon). Spells ending (or spirits disappearing) on sunrise or sunset is also clearly observable. So they can plan around that.
Other game rules are probably harder to percieve - rerolls, damage rolls, because there are many variables that are difficult to control, so it will be broader strokes (10d6 vs 6d6 spell, sure, but 9d6 vs 11d6 might be hard to say.)
