[tor-relays] No guard flag?

Hi, I'm running a relay node [1], and it's been up for a few days over 68 days. I was thinking it would get the guard flag around then. It has yet to get the flag or have non-zero guard probability. Any idea why that is? Or what I could do to get it to be a guard? 1) https://globe.torproject.org/#/relay/741488D89B860E59D6391ACA27A157E87EB533F... Thanks, G
