Hello!
Thank for good package.
I have a problem about network usage stats.
I take the usage data from before to the time of collection and send it to the server every day, like below.

I think the data will increase every day, but it doesn't seem to be as I expected.

You can see, the data on May 30 and May 31 has no problem, but on June 1st, the data is reduced. this seriously affected my statistical calculations.
