I just finished off possibly my best NL session ever, but unfortunately I had to beat the hell out of the same guy repeatedly to do it. Almost all of my profit came from him as I took about 3 stacks off him. It was the 1st time I ever felt really bad at a poker table. The last time I even almost told him to fold and bet out instead of c/r'ing almost wanting the poor bastard to fold (but not really).

He was already down 2 stacks supposedly before I got to the table.
My very 1st hand - in the BB.

With $10 in the pot already and only $22 left, I almost kinda have to push with all those outs. I'm actually the favorite after the other fish folded. This was the biggest pot I'd won all month.

So he's down 3 stacks now and loses a little more than half another one when he flops trips and is outkicked.

So now he's down about 3 stacks. And I crush the poor bastard again. Usually I would c/r here, but I felt so bad that I actually tried to give him a way out, but he couldn't fold. Part of me wanted him to fold as you can see by my comment after he called.

He's now down about 5 stacks at the table. He lost another $10 to a fish when he made a move in the SB w/ 44 then semi-tilted to the push (Pusher was a fish though). Fish had open limped OTB and only had $10 left. He raised in the SB and fish pushed. He called and fish had KQo and hit 2 pair.

He's down about 5.5 stacks now and then plays this SICK hand against the same fish.

Now down 6.5 stacks. By the way, what the EFF is it about 44 at Full Tilt. Turns into a freakin set almost every time. This guy is having a horrible day with QQ.

Just before I left he made back a stack. Notice how I would have stacked him again on the river if I was maniacal enough to call with the BDFD+GSSD.

I know I personally have had significantly worse sessions. And I'm pretty sure I haven't had the worst session in recorded history. Here is a screenshot of the aftermath of a pretty sick session (Prahlad raping some guy over and over at $50/$100 PLO)

Good lord that's terrifying! Personally I've never dropped more than 3 stacks at the same table. 4 would be my cutoff for any single table in NL. For limit it's probably 2 per table or 60BB.
