How much should an app with 50k active users be earning?

Info: My app has 55k active users.

Daily banner impressions ~20k
Interstitial impressions ~1k
Fill Rate~80%
eCPM ~0.5$

That translates to roughly 10$ daily… I’m curious what other apps with similar stats are earning?

Flurry reports: 30k DAU
Ads: 1.625mil banner/300x250 impressions

I don’t trust Flurry… or else each user saw 54 adverts on average!
