how frequently admob refreshes the report?

I am new to Admob and wanted to know what is the refresh rate of the report that we see in admob. Is it every 30 mins or 1 hour? Or it varies depends on the impressions requests received by Admob. Thanks.

Guys,

Please help me understand how delayed is the admob dashboard refresh. Is it 2 or 3 or 4 hrs delayed though it says it can max be delayed upto 48 hrs.

I have found they updated every 30 mins to an hour. After 24 hours they tend to re-adjust the reported earnings for the previous period (mostly in your favour), at least on my account.
