pip = health point/health unit.
Is there a 1 pip rule or is there no 1 pip rule? Because yesterday it always worked, today it didn't work.
I'd like to be certain: is it or is it not?

The 1 pip rule: when you receive damage enough to kill you, you are left with 1 pip instead of being killed (even if typically you get 6+ pips damage and you had 2 pips health, you're still left with 0.5-1 pip health, 90% of time its 1 pip).
This happened many times yesterday. I was left with 1 pip after receiving a blow that was supposed to be fatal. Today I was killed many times in a row while having 4+ pips of health (sometimes 6). Straight to zero.

So I'll repeat my question:
Which one is correct behavior? Possible answers:
a) being left with 1 pip of health, no matter the damage, when you have more than 1 pip of health.
b) receiving full damage - if it kills you, it kills you. No matter how much health you had.

I think variant a) being left with 1 pip of health is the correct behavior. Because thats the only way I can enjoy the game, not having to worry if I have 6+ pips so I don't die suddenly with 1 hit.
If you know the correct variant, please tell me (since I've seen them BOTH at work).
