Hey,
I could likely come up with this if I sat down and experimented with the formulas for a while, but I really feel like they should be listed somewhere and better documented and I'm really hoping someone else has already done the legwork. I don't even know if 'order' serves the same purpose in both formulas.
- RANKAVG says "order—[optional] The arrangement to use to evaluate the range"
- RANKEQ says "order—[optional] The method to evaluate the range"
What are the possible values?
What are their impacts?
What is the default if no order is declared?
