Holyrood 2016 result predictions given current polling.

Obviously, it's more than a bit early for doing projections like this. Having written the algorithm for implementing the Holyrood FPTP/AMR system and applying it 2011 data to check that I was understanding it correctly, the effort to apply current polling to predict the 2016 result was minimal. Take with a few kilograms of salt.

Current polling:

Moving average of latest polls for constituency vote:

Party Vote Share (%)
SNP 50.23%
