[tor-relays] Why is there a difference in the amount of data tor has sent and received?

Hello list,

So when running my OBFS4 bridge I noticed something, tor recently popped up with a message saying “I’ve sent 30mb and received 104mb.” Why is there such a big difference in the amount of data my bridge has received and sent?

Info – tor 0.3.4.8 running on Windows 10 (Although tor seems to think it’s running on Windows 8 for some reason)?

Thanks.
