Beating the bubble and winning more

hey all,
i play $10 sng's on pokerstars and im looking for some help to more consistantly beat the bubble. I started about 2 months ago and my bankroll is up a little. whilst im happy to be ahead i seem to be stuck and i would like be able to build my bankroll and win more consistently. i recently purchased poker office, which shows 50 $10 sng for a profit of $43 (10 firsts, 4 seconds, 3 thirds), and 15 finishes in 4th or fifth which i think could be improved. is this too many bubble finishes? i try to be much more aggressive on the bubble but it seems to come unstuck a lot.
any insight, tips or articles to profit more and more effectively beat the bubbles would be greatly appreciated. also if any more stats from poker office would help let me know.

cheers,
andrew
