difficulty now is 1.3 . 100KH/s will get you 33/38 SBC per 24 hours
1.3 difficulty will get you 77.37 SBC per 24 hours.
What's wrong with you guys? Where are you plucking these numbers from??
Experience mining, pools.

Difficulty is 1.30, earlier today at 1.02 difficulty everyone was averaging 0.48 SBC/day per khash (100khash/s=48SBC daily). So at a difficulty of 1 the daily SBC rate is 0.5 SBC per khash. I dunno what else to add, you should know the math better than me ;P
