It would seem as inverse power leveling at first glance.
Make a character that has as low attributes as possible.
When you start playing, alwas level up +1+1+1 until you max out your skills. Go to jail and reduce your skills, so you could level up again. This is just because you can degrade your skills but not your attributes. This would lead to a situation that you have many levels because the +1+1+1 level ups. So, once you get to the 100 for all attributes, you should be at a much higher level than through +5+5+5 leveling (actually 5x higher level).
One thing to consider is that it is MUCH harder to play, when you're leveling your attributes like a snail.
On the other hand, the +5+5+5 power leveling would never give you this much health.
I didn't do any calculations, but I guess this way you could reach much higher levels. But I guess the price of doing it is a torture. You should spend at least two thirds of level through skill decreasing through jail.
Please, don't flame, just because this is my first post. Try to understand what I'm trying to say.
Again, didn't make calculations, but maybe it would be better to do +1+1+5 leveling at start while increasing endurance (for the health gain), and later switching to +1+1+1.
