Podpress stats for ‘feed’ vs. feedburner stats

I am using podpress and feedburner. The stats I’m getting from feedburner are very different from the stats I get from podpress. And I know feedburner only tracks downloads/plays from my feed. So I’m looking at the dashboard where it breaks out ‘feed’ ‘web’ ‘play’ ‘total’

I’m comparing the ‘feed’ number from podpress to the feed number from feedburner and they are significantly different

Anyone know why or which one is right?

I’m also curious what ‘web’ tracks on podpress. Anyone know? And how is ‘web’ different from ‘play’ or ‘feed’ and is there any overlap?

thanks
