I'm using the second method of HP washing (where you put one point in HP and then proceed to dump all your excess MP into HP). The problem is that when I took one point out of my main stat to add it to HP I only gained 20 HP on my fighter. I immediately realized this was incorrect so used another AP reset to try and remove a point from HP and put it back in my main stat but it wanted to remove 54 HP if I wanted my point back in my main stat. This is super screwed up. By this logic I am gaining 20 HP when I add points into HP and losing 54 HP whenever I take it out. Now I'm stuck with this point in HP that I no longer can take out unless I want to have a net loss of 34 HP using this Reset...
If I remember correctly from when I HP washed my pally, it showed +20 hp on the screen, but it really added 50-54 hp.
You are gaining the correct amount of hp if you look at the difference after using the reset. Also unless you have no extra mp then there is never a reason for you to remove a point from your HP.
