This is very interesting and it would be very useful to see the Election Rules they used. I don't think these are BC-like rules,
i.e. applying the Weighted Inclusive Gregory Method (WIGM) of transferring surpluses. I suspect the rules are more like the STV
rules for the Australian Federal Senate elections, i.e. Inclusive Gregory Method (IGM).
I suggest that, because when Grace Aaron's surplus is transferred (Round 21), they show only one transfer value (cell BK7 =
0.04476852). But Grace Aaron then held ballot papers of two different values, namely 1.00 (her own first preferences and all the
first preferences transferred to her from excluded candidates) and 25.5 ballots @ 0.213867(etc) transferred from the surplus of
W01-Ahjamu Makalani. If they had been using BC-like rules, they would have had to apply two different transfer values. Instead,
they have averaged, the way the Australians do (and that is fundamentally flawed).
They also seem to have used arithmetic of indeterminate precision - there is no truncation to a stated precision. Some results are
shown to 14 decimal places, others to 16 decimal places. The differencing values are shown to 29 decimal places. I don't know how
they did these calculations because my version of Excel (Excel 2002) cuts out at 15 decimal places. They start with 2246 votes, but
at Round 5 they have gained nearly one whole extra vote and then they progressively lose votes. If the calculations are done
correctly and consistently, the vote total at the completion of each Round should always be exactly 2246.
Although I can follow the calculations, it seems illogical to me to have put the numbers of transferred votes in a column before the
numbers of ballot papers from which the vote values were calculated.
