Game Discussion - mixed polarity actions?

[carrie]

Let's say virtual characters do 3 good things, then 1 very bad thing:

3 good things * 1 point = +3
1 bad thing * 3 points = -3
total polarity = neutral

3 good things * 1 point = +3
1 small bad thing * 1 points = -1
total polarity = +2 points

noticed in one virtual day -
virtual character does 5 or 10 good things
then bad day happens, loses all polarity



question:
- would above formula be correct?
- what virtual actions could be defined as STO and STS?
- what virtual actions could help or reduce polarity?
