This may help. The following table shows, the time of declaration from the 1997 referendum (add a bit on to get the estimated time for this month's vote due to the higher turnout), name of authority, size of electorate (from 2011) and (importantly) the percentage required to secure a Yes 50.1% vote based on a weighting from the 1997 referendum and the 2011 Holyrood election. So Yes should be aiming for over 55% in Glasgow but 35% in Dumfries and Galloway is still within range for Yes to secure a nationwide Yes vote. So assuming that Clackmannanshire and South Lanarkshire are first to declare, we should be looking at around 53% Yes from those two authorities to put Yes on track for victory. My understanding is that the vote will be announced by each local authority as the votes are counted so no need to wait until the entire country has been counted before we find out the result. We should have a good idea of the winner by around 3.00am I think.
