27
The number of new voters and total voters should be rounded in texts as they are estimates.
28
The reason the number of seats don't add up in the "Totals" tab, as some of the seats are dublicate (two or even all three categories would flip the margin).
29
As such the Newvoters, UKIP and Green tabs will contain duplicates
30
The UKIP+Green tab contains five constituencies that are not included in the other sheets (and in this sheet totals), as the UKIP of Green voters alone wouldn't flip the margin, but their sum could
31
