Here's the average change in share since 2017 in the 11 recent by-elections in Scotland.
Con +1.5 Lab +0.8 LD -0.1 SNP +3.8 Grn +3.8
Would the Green figure be less if you counted us as -5.2% in Almond and Earn for not bothering to put up a candidate? If you get counted as + whatever for putting up a candidate where you didn't before, then the reverse is only fair.
