global average

I have seen threads about this but, no one has actually said how to calculate for it. I really want to know if I am sub-9 and I want to get my globals for all my events. Thanks in advance!

I have seen many people describe their "global averages" many different ways lately, but i have not seen a real definition of a "global average". I know what it means to me, and the basic concept, but how would you guys define it, and/or calculate it? I have seen people do ao1000's to figure it...
