Bankroll Management Revisited

I have not had much time to play the past few days, but when I have I have continued the decline in my bankroll.  I now sit at $1200.
Looking at the fluctuations in my bankroll over the last few weeks I see ups and downs of 25-50% several times.  This tells me that my bankroll management system currently in place is too aggressive.  I do not want to see these time of swigns any more.  They are great when they are on the way up, but the risk of going bust seem too high still.
I was allowing myself to bring up to a maximum of 10% of my bankroll to a cash game at one time and I often played at two tables at once so really 20% was at risk.  I am going to cut that in half so no more then 5% will be brought to any one table.
the mini FTSOP is starting Sept 8 with a $22 buyin hold'em tournement which I am going to try to play.  If I make it deep into the tournement I will start blogging about key hands.  I may try a couple other events as well but this things tend to last a good 8 hours so it may be difficult to get more then one or two in.
