did you mean .05/.1? finishing up 3 bucks at a .5/1 table is definitely not significant....

and, btw, here's a little more perspective on the four of a kind thing. my numbers will be a little off but it'll give you a ballpark.

starting with a pocket pair, the odds of someone getting four of a kind is on the order of 1 in 4000 hands. so, sitting at a full ring game with 10 people, odds are you will see one four of a kind per 400 hands. that's about 1 four of a kind per 7-8 hours, for the whole table. less, considering that you will get them sometimes.
those numbers probably aren't exact, but that's a good ballpark.
