Yes, this one works. But there are still some interesting peculiarities. Example:
We have three sates with population A:5, B:3 and C:3 (millions I guess). Seats will be allocated in the following order: A, B*, C, A, B*, A, C,... - Three first seats go to the three states either based on the "at least one seat per state" rule or by starting the algorithm from "zero seats" - I used * to indicate where B wins the seat by lottery (instead of C) The strange thing is that the fifth seat goes to B by lottery but C will not get the next seat although it was already entitled (tie) to the previous seat (and B and C are identical states in the sense that they have exactly the same population). Divisor methods like SL/Webster provide ordering of the candidates/ seats by default and they may be nicer to use in places where such ordering is needed. I however tend to think that the Alabama paradox is not a sufficient reason to abandon use of LR/Hamilton in seat allocation to the states. LR/Hamilton does the allocation in a perfectly rational way that can be considered to be ideal (at least from one point of view). LR/Hamilton (Alabama paradox) may look bad to the audience if presented so, but it is another question if it is bad or if it looks bad to mathematicians.
