Stamina in HP Growth Calculation

To make (Stamina * Level / 4), couldn't you just take Madsiur's patch and make the HP growth table value match the level the character has?

If the HP table is 10 at level 10, is it just like making Stamina * Level / 4?

Or is there something I'm missing (which wouldn't surprise me)?

You are correct, but that still makes Stamina affect growth, not state. I.e. raising Stamina in the later levels doesn't cause you to retroactively gain the HP you would have gotten with the same Stamina in the earlier levels, nor does it allow you to temporarily gain HP from equipping Stamina-boosting equipment.
