Not sure if everyone knows as common knowledge, and not sure if it is a changing figure, but the 7/10 switchover is currently at what appears to be 45% of top MPR. For some reason I thought it was 65%, so that is why I was surprised (and am posting).
Feel free to discuss or even add to the Wiki (I didn't see it, but I can never find anything on there in any case). And before anyone says "add it yourself", I won't add it myself because there are folks out there who have done a lot more on the Wiki and have a better idea of where such a fact should go (if such fact is even deemed wiki-worthy to begin with. That I know not). Just because one "can" do something does not mean one "should" do something. *smile*
