Finding the critical algorithms and determining these properties for each one is the hard work now. In the ASCLWG discussion I didn't intend to demonstrate past the case at hand then, namely the first two costs above. Maybe I was blissfully ignorant of the third. Now I'll have one more hint next time I find some Mneson function slow. Thanks for the byte :-)
