Thanks for confirming, as I said, that the Exit poll 'predicted number of seats' is calculated on a seat by seat basis.
Jeeeez
Look again at what I wrote, and read that article linked to above about the methodology of the exit poll and its outputs.
For the final time: the predicted number of seats for each party in the exit poll is calculated based on a seat-by-seat analysis, which itself is calculated on a mixture of actual polling outcomes and statistical algorithms applied to those numbers (and changes in those numbers between elections).
BUT: the outputs for the exit poll are not given on a seat-by-seat basis.. They are only given on a total-seats-per-party prediction basis.
The seat-by-seat predictions being used by the BBC are a reverse engineering of the exit poll's output. They may indeed differ for any particular seat from the predicted result calculated in the exit poll's internal workings.
Maybe that makes things clearer. Maybe not. Either way, I'm now done talking about it
