Sorry about that aston and immad. Even I believe its not 0.5 deterministically, but I think it averages to 0.5. The system appears far more adaptive/dynamic than a completely deterministic model as suggested by the formula. But again, its a model.
My friend, up-voted me once each for two separate comments, but my Karma remained the same. As a matter of fact, I observed something similar with the submissions as well. This could imply the following -
1. Karma calculation is not interrupt driven, but its timeout based (I probably hadn't waited long enough!) OR
2. The weight for the comments (/submissions?) could be a function of user Karma, with an average of 0.5 (I probably did wait long enough!) OR
3. My friend's up-voting was suspicious (Highly doubt it!!)
Errata - My friend up-voted me on two different comments, once each. My score should have increased by 1 Karma point going by the 0.5 weight for comments, but it did not, immediately.

My bet is on 1 and/or 3.
