Few questions on guild ranking

I asked this question a while back on this thread https://www.spacetimestudios.com/sho...uilds-May-2019, but I didnt get an answer, I hope some senior members/ mod or dev can help me understand few things.

Q1. Why is Founding Date a component for guild ranking?
Q2. What is Avg Account Age (d) component? How it affects the ranking?
Q3. Now that PVE kills is not a parameter for top player LB is it okay to remove it from guild ranking as well?

I am putting the 3rd question out there because I feel that out of all the parameters PVE K/D is the most exploited one. I personally know guild masters who keep dummy accounts that farm pve kills 24/7 or dead/banned accounts that have millions of kills.

Please try to be on point with the answers, appreciate your views on them. Thank you.
