Still, by the time you get to 7p and 8s all bets are off, since now spin-orbit coupling is severe enough to trump quantum-level-only placement. I forgot to mention the effects of differential shielding in f,d,p,s in my last post. Any comments?

Labelling the groups
It sounds like nonsense to say 'Helium is an alkali metal', but if we adopt Janet's system for labelling the groups, the problem disappears: 'Helium is at the head of the s2 group, and hydrogen at the head of s1 '. On this basis there is a problem with elements whose distinguishing electron belongs in the 'wrong subshell'; by that criterion, for example, La and Ac belong in d1, but we can base ourselves on the fact that in most cases the nth element in the f-block has n f electrons. What we are building is ultimately a pattern of patterns, not a table of properties. It is not the properties that dictate the pattern, but the patterns explain the properties.
