For Motheroffourdragons - and also (relevant to this thread
) anyone else interested in how the state broadcaster can alter perceptions.
Here is how @scotelects (and everyone else except the BBC
) reported the facts of Scottish council elections. Although there were a few outlets (eg the Guardian, ITV and a few others) who reported the SNP has having a notional increase of 31 seats 
Because that's what they were: notional. Parties didn't put forward candidates in these notional seats (eg my ward changed from a 3 candidate ward to a 4 candidate ward) and/or people's 1st, 2nd, 3rd etc preferences would have been different.

The other thing that was interesting when I was looking for bald figures to provide (there are others on @scotelects) was a) the predominance of the BBC's "loss" figures and b) defensive articles from the BBC about "how it calculated the results" 
1st preference votes were exactly the same percentage between 2012 and 2017 for the SNP: the percentage changes are from Labour to Tory - resulting in the gap to 2nd placed party (in number of seats) increasing from c30 to over 150
