I wrote a post back in 2011 I think regarding the ridiculous 12-hour duration of a Ready-Go. No one seemed to understand back then that you don't need to enter a RG unless you are ready to play; you won't miss out on a RG of that type as there is always one instance of every RG available. And today, 9 years later, no one still seems to understand that - players enter a RG and then wait nearly the full 12 hours to play it, meaning those of us who enter and play straight away have to wait the full 12 hours before we can play another.
The only reason I can see why anyone would want to take 12 hours to play a RG is collusion. There is nothing else to be gained by not playing it as soon as you enter.
Keep the 12-hour RG's if you really have to, but please can we have some RG's that last no more than 2 hours from time of filling up. A 9-hole game takes no more than about 15 minutes, so 2 hours is more than enough time to play the game, and then we can enter another instance of that RG. This way we can comfortably play 5 or 6 of the same RG each day if we want rather than just 1.
