a) is it actually HTTPS traffic?

b) are the bytes going through the proxy 2.2Mbps or 240kbps ?

I ask because Google/YouTube and Facebook are services using HTTP/2 with
high compression features as much as possible. So while the proxy is set
to transfer X bytes per second, when hidden inside "HTTPS" those X bytes
may show up as 90*X bytes of traffic when decompressed by a Browser.

Or the transfer may be QUIC protocol, completely bypassing the HTTP the
proxy is counting.
