Well,
I think most of us can understand your decision and do agree with.
I voted for Paul's M1 too.
But nonetheless I must protest against this kind of decision-finding.

I repeat it again: It is not stated in the rules.
Further it is also a question of acceptance...and transparency.
No explanations about the whys and whats the staff based their decision upon.
Please do not get me wrong: We all trust in the staff's competence and trustwortiness.
And would it be that difficult to select two winners?
Accidently I can serve with an actual
example of the current football championship.
The season is not still over but if you look at the second place you will find two teams.
No one has been deciding (and will not) about their position beyond the rules.
Therefore I recommend you to revise the decision.
