Looking at the advertised bandwidth vs bandwidth history from Tor Metrics[1], it appears that guard relays see much more traffic than exit relays. I think it might be partially because guard-only, guard-middle and guard-exits aren't separated, but would it really skew the numbers that much?

Don't forget that some traffic enters through guards but lands on hidden services, skipping Exits.
But hidden service traffic makes up about 0.01% of Tor traffic.
Total is about 75Gb/s: http://rougmnvswfsmd4dq.onion/bandwidth.html
Hidden services are about 900Mb/s: http://rougmnvswfsmd4dq.onion/hidserv-rend-relayed-cells.html

0.9 Gbps / 75 Gbps = 1.2%

Hidden Service traffic goes through two Guards and no Exits, Exit traffic goes through one of each.
That said, the most likely explanation isL * almost every Exit has the Guard flag, but only a proportion of Guards have the Exit flag, and * the bandwidth allocation algorithms give relays with Exit and Guard flags all Exit and no Guard traffic, because Exits are rarer than Guards.
