I want to clarify my methods here, so that nobody is confused or upset by tomorrow allocation...
In allocating SCs for Round 4 (as for all rounds), my primary goal is to minimize the difference between all players' picks and their actual SC. [If you number picks 1 through 8, where the most desired center is 1, then I am going to try to minimize the sum of SCs as actually allocated across all players]. As a tie-breaker between equally good allocations, I will consider which players have lost out in ties already (yes, there have been a few).
For example. Let's be hypothetical. Assume a five-player game. Frodo has lost out on one of his picks in an earlier round. Nobody else has. Everybody picks Hobbiton as their #1 pick. Everybody has Barad-Dur as their last pick... except Frodo, who has it at #2. Picks for other SCs are evenly distributed so that everybody can get their #2 pick so long as Frodo gets Barad-Dur.
If my first consideration was the remedy of previous ties, I would grant Hobbiton to Frodo. But I won't. (Instead, I'll give it to Saruman, who speaks so smoothly). Instead, Frodo will get Barad-Dur, because it minimizes the SC ranks across all player sets.
In other words: just because you've missed out on an earlier round does not mean you're sure to get your choice in this round!
