I signed up for a couple before I at work yesterday knowing I had nothing going on last night and would be able to play after dinner with the family and loading the trailer to go racing this weekend. Loading the trailer turned into rearranging the whole inside. I finally got to play and finish those 2 this morning at about 1 am. I think both had around 2 hours left. I just have just WD because I was so damned tired but I usually post no matter how bad it is.
In that instance I was lucky they allow the 12 hours. I do like the idea of being able to register in the next one after you've played the previous instead of waiting for everyone to post. But the opposing view of the same people winning the same RG over and over makes sense too.
If you only play 2 or 3 specific RGs I can see where the wait is an issue. I usually donate to way more than that and rarely do I have to wait. Thank goodness.
