No problems Alexus, and you definitely raise some points that I've thought about from time to time. In response to some of the things you wrote...
I agree to a certain extent. I don't think it's necessarily worth investing the time to do the splits, and most definitely what your goals are should dictate the kind of plan you have for your mobility. But I really do think that some of the movements are overkill only in the sense that you (meaning, anyone trying to get into his positions) simply may not have the requisite mobility to do it yet.
Funny, you and I both used the same video as an example to illustrate our point! I absolutely know what you mean about the wrenching feeling. Pretty yuck. But, that position should be viewed as the goal, not necessarily the start point. As I said, try moving your knee out from the wall initially. Alternatively, by doing a stretch prior to that one that biases the hip-flexor and hip-internal rotation you can give that area slack, so by the time you move to that particular stretch you've already "warmed up" as such.
As to the technique, that was poor wording on my part. What I was meaning is, it's all very well talking about technique, but if you don't have the requisite mobility to maintain those proper positions under load then it means nothing.
There is only a trade off between flexibility/mobility and strength/stability when you're talking about hyper-mobility. I think a lot of people who do weightlifting truly do underestimate how mobile you should be to do this sport well. To me, it's about readjusting the goalposts, so to speak. Take any Weightlifter at the olympics. Get them to do the stretches and mobility work on the MWod and I guarantee they'd crush it.
