Good to know.

I know my relay can't hit 100% of its capacity 24/7. I want the 
"consensus weight" and the "advertised bandwidth" to see my bandwidth.

Makes sense. I hope torflow gets replaced soon.

I thought of many reasons: my router, Verizon's backbone, Verizon's FiOS 
edge network, or just Tor's crappy load balancing system (which I hopes 
gets fixed soon).

I set up another relay to increase my bandwidth. If that doesn't help, I 
will look into replacing my WRT1900AC with a pfSense or Ubiquiti box.

I probably won't. Aside from the obvious reasons, I won't run an exit 
from home because:

  * I would get blacklisted from too many websites
  * Most ISPs don't want to give you you more than one IPv4 address to 
separate Tor traffic from everything else unless you go business class
  * Verizon would probably notice my "exit" relay from abuse complaints 
and then would say "you can't do this on FiOS" unless I go business 

I run an exit from a dedicated server (not a 
OVH/Online.net/Scaleway/Hetzner, but one from a host called GTHost).

You're welcome.
