Tor browser update ping statistics have jumped since August 8th 2022

Yesterday I have noticed tor browser update stats have jumped since August 8th 2022.

The webstats that we publish are computed by crunching our web servers logs and computing how many times a URL is being hit. Then we send this data to a sql DB and we compute the following queries:

The query and regular expression used seems pretty basic and has not changed in a long time, could it be that something else has changed on tor browser side? Or do we simply have more clients?
