I'm going to close this thread because there are other threads that also would like my thoughts. I think there's enough here for most and at least the original question was researched and answered.
Part of the reason to close the thread is that the thread has become OMNI itself. It seems that now i have to go back and qualify the stats for RBP for OMNi and do a statistic analysis, etc. I apologize, but really i think my time available to FlyerTalk is best spent on helping out the general membership of FlyerTalk. Something I enjoy and usually i don't have to get drawn into some analysis paralysis. Suffice it to say, there are some members in OMNI that will have some of their posting privileges curtailed because they fail to meet the "play nice with others" doctrine on FlyerTalk and elsewhere in the world. All other members, please continue to enjoy the casual community spirit of FlyerTalk – whatever the topic.
