Polo Rules

People need to stop making assumptions about NA polo just by reading LOBP.

True, but if that's aimed at me it's more about not "getting" the ruleset/how to ref. I'm still clueless even after digging up old threads on LFGSS and LOBP, maybe the next NAH ruleset will help clarify things. It seems as if the way I view most collisions is incorrect.

I think it's important to have a different amount of time each game

Agreed, this has been discussed in the past, it's the better approach (to avoid cheating).

Perfect, with 3 seconds between each signal.

The purpose of the whistle is to randomise when the players start the charge, this ensures you can't cheat (go a small fraction of a second before you should, etc).
