Actually no, not yet. But that is easy to see, just keep an eye on your last 7 day averages. If your average is higher than his, then it means that even if in one day or another he flushes more than you, in the long run you're always winning.
Right now I'd say you guys are almost neck-to-neck and pushing hard... If you slip he'll take you down, if he slips then he'll be eating your dust :P
Also, congratulations to SlackPawn who jumped directly to his deserved second place now that I merged both usernames
And an honorable mention to 72CJ5 for the biggest flush of RC5 blocks I ever saw in the contest! :D I dare you to keep it up like that! :P
Oh yea, and you have jumped directly to second place too!
