Guild Status and Faction Reward?

In conjunction with this weekend's PVPX, I would like to pose this question.

How does Guild Faction point reward system Work?

It says depending on how long you have been in a guild, but thats very vague. Is it based solely on how long you have been a member, your status, hours logged, or GVG combat within the guikld.....?

I did a search and didnt find much, I am very interested in these reward especially with a 2.5X extra incentive coming up this weekend.

Directly from the Guild Wars site...

That aside. Normally you will gain full faction in GvG when you've been a member in the guild for a week (or was it 2wks?)

huh ok - if it helps I'm in my current one over 2wks and I got 300 faction last couple wins in GvG

300 is the minimum, it's what you'll get for beating a team beneath you in the ladder.

This explains a lot. I thought it was strange that I was only getting 64 faction points for GvG victories. It feels like i've been in the guild a while, but in retrospect it's probably still less than 2 weeks.
