My Downswing Has Hit 300 BB

[MEbenhoe]

So I'm allowed to make a post about it now right?

After having dabbled in 3/6 and 5/10 many times before while playing 2/4 full full time, I recently finally made the move to playing 3/6 full time with a more than sufficient bankroll. When the party bonus came out, for some reason or another I decided I would clear the bonus at 2/4 (Possibly a stupid decision considering I'd been winning at a decent rate at 3/6 early on in my transition). Well while clearing the bonus at 2/4 I suddenly went on a nice 300 BB downswing. Honestly, I've felt that I've been playing on top of my game, but have just been running bad for a few days. However since I might be bias, I figured I'd see if you guys could spot anything that might be causing this.

My stats at 2/4 before the downswing were:

VPIP 21.47
VPIP from SB 30.32
Folded SB to a Steal 73.24
Folded BB to a Steal 65.96
Att. to Steal 29.35
W$WSF 36.13
WSD 35.43
W$SD 49.06
PFR 10.09
Aggression factor Flop: 2.02 Turn: 2.18 River 1.69 Total: 1.95
Folded to River Bet 36.86
BB/100 3.61

During Downswing:

VPIP 22.65
VPIP from SB 29.71
Folded SB to a Steal 90.00
Folded BB to a Steal 46.67
Att. to Steal 31.58
W$WSF 27.40
WSD 34.48
W$SD 40.53
PFR 11.52
Aggression factor Flop: 1.98 Turn: 2.14 River 1.38 Total: 1.79
Folded to River Bet 38.89
BB/100 -10.05

What I noticed is that most of these numbers are very close to there normal standard, however the W$WSF and W$SD are both much lower than usual. Is this a sign that I'm simply running bad, or what are some other possible reasons? Given that I still have a sufficient bankroll for 3/6, can I move back up to 3/6 or should I stay at 2/4 for awhile, possibly even switching it up by playing some 1/2 6 max?

Thanks, any comments appreciated.
