50.1% pro-independence vote if you only include the SNP, the Greens and Alba
50.4% pro-independence vote if you also include the Scottish Libertarian Party, Restore Scotland and Scotia Future
50.5% pro-independence vote if you also include independent candidates who are well known to support independence, such as Andy Wightman and Martin Keatings
And that still doesn't mean 49.5% can be assumed to be the anti-independence figure - for example as far as I can see the Women's Equality Party don't have a policy on independence, so have to be treated as neutral. The Scottish Libertarian Party directly confirmed to me on Twitter a couple of weeks ago that they still support independence, which ironically means that votes for Mark Meechan, aka Count Dankula (a former UKIP candidate) can be regarded as pro-indy votes.

I have an article in The National today about the impact of tactical voting on the regional list seat allocations - you can read it HERE.
