Oh yeah, well, after my extensive inspection of the belay anchors I had come to the conclusion that the picket system had 7 cumulative crust-layers and a non-shockload impact rating of 7.8 kN, and my voluntary backup from the buried shafts of one iceaxe and one ice tool provided a 0.9 kN redundancy..
Of course pickets are only as good as those placing them. I personally have never placed a picket that I would want to fall on. But then again, I've only ever placed pickets for fun...
