I'm sure you could make your system quiet, watch your packet/byte
counters, download a few different things (youtube videos, FreeBSD
iso's, whatever), on and off tor and post the results.
You could do the same with a fixed browsing session (many small
html) instead of single data files. Clear your cache, etc.

Encrypted data can be much less if the algo compresses it first.
A bit can be added for each stream due to key exchange.
Then there is routing setup.
Your results will say more.
