blogger stats gone mad?

From the 8th 'til the 19th of June, my blog has had (according to blogger stats) 3, even 4, times the nuber of hits it has had previously.

Hooray, everybody likes me! - or?   I have had the "ordinary" google statistics on the blog from the beginning. Ususally blogger stats and google stats have showed similar numbers (not exactly the same, but if one says 32 pageviews the other says 36, or 30). Since the 8th, google statistics continue to show "usual" hits (between 25 and 60 pageviews per day), while blogger stats shows numbers from 100 to 200 per day. Yesterday blogger was back to normal (matching numbers, 56).

Has anybody else seen something like this? - just curious.
