I looked at my usage this morning and thought it seemed a little high at 1.1GB
A peek at the download status meter shows about 409 MB used on June 7th:
A look at the History shows about the same:
Looking at Glasswire for my main machine shows usage of 253.7 MB but I do have a router and wireless devices:
A look at my router for that day shows total usage of 252.58 MB for all devices:
Hughes claim of 408 versus my routers claim of 252 is a pretty good descrepancy.
Any thoughts?
