Differences between new and old stats (2.1.28)

I know that there is a similar thread that was concerned with the number of cards due tomorrow being diffferent. My problem is that my total reviews and time reviewing for the whole collection are different on the new version of statistics. Namely, the new versions shows smaller numbers.

The old stats say that I have 32 hours review time and 12000+ reviews, while the new statistics say that my “running total” is 1.24 days (little less than 30 hours) and total reviews are around 10000. Am I misinterpreting the new statistics somehow? Or is this some sort of a bug?

Thanks for the report; it looks like a typo was preventing early reviews from being counted. I’ll fix this in the next beta build.

Thank you very much.
