The organiser of this particular competition has publicly invited suggestions for rule changes on more than one occasion, most recently yesterday. So far there have been one and a half serious suggestions, and only then for minor tweaks, so the format must be somewhat popular. I understand BN's objections but the experiment seems to be going quite well. Also, with the existence of the automated prediction competition, there's no room for me to run an almost identical game within the forum.
In relation to my fixture this week, if my opponent hadn't gone with so many 'safe' picks - ie teams who 'should' be winning their games - he might have beaten me.
