The results look pretty good -- better than I'd expect, considering how these live games are raked. Looks like you're getting around $4.50/hr. A good result would be one large bet/hr, but considering the rake at these low limit live games, you are likely to be under that.
I do see some problems there: -300 and -260. That's onehelluvalot to be losing in 3/6FL. That's four or five buys down the drain. I would question if losses of these magnitudes aren't pointing to tilt control problems. Let's look at the potential winnings had you cut your losses after dropping a couple of buys (-120). You would have had $1040 for a $13/hr win. That's running good, very good.
"Does anyone here strictly play fixed limit 3-6? What are your results after promotions? After winning days?"
I avoid it like the plague, and anything less than 10/20FL (the occasional 8/16 game excepted) isn't worth my time. These days, the rake at these low limit games is absolutely brutal and makes them unbeatable. Used to be that finding good FLHE games wasn't difficult, even at stakes as low as 1/3 or 1/4. That was 25 years ago. Today FUGGEDABOUDIT!
This is short sighted stupidity on management's part. Give the low limit live players a break, and cultivate them for graduation to the no-limit games. If I were running a card room I'd offer these small games with no rake. Give these fishies a break, give them a chance to win, and they'll stick around, hopefully to graduate to the no-limit games. You keep running off the fish and there won't be any games. It's especially foolish post Black Friday.
