Lol, no, that would be too tedious. Don't worry about not upgrading, all bosses will take at least one hit with whatever nail you have.

What the program does is display an enemy's current HP briefly in your Geo counter when you hit them, so all you do is add that value to the damage value of your nail at the time and you have the enemy's max HP.
