Those are two very different elections scenario under different circumstances.
1. There was voter suppression in NRM and swing counties on 26/10
2. Alleged withdrawal of a major competitor so voter turnout of the other competitor was going to be naturally lower
3. Voter fatigue
Therefore 8/8 cannot be a base for 26/10 analysis. It's like comparing the candidature of RAO against MaDVD or SKM and what the turnout would be in those scenario.
