This had been brought up before...Unfortunately, no we cannot have the actual 'health points' for a given project. In order to do that, we have to have the dynamic data from Sony. All in all, it's a lot like the breath window (I'm guessing, I don't know because I haven't tried), where it's just a percent progress bar, and you can't put numbers to it.
Think of it like sprinting. The amount of power you have changes as you gain levels, but it still takes the same amount of power every tick while your sprinting. I don't know exactly how the crafting works (Haven't taken the time to check it out), but from what I've seen, it's all a bunch of equations and logarithms that change as skill and spell levels change, and what level you are in relation to the item being created.
However, I'm sure it wouldn't be too horrible for Sony to implement this, after all, I'm sure every recipe has a given "health" value that must be maintained for each given quality. Maybe we'll get lucky and they'll implement it sometime...
