4 for yesterday because of the binerdle misdirection.
A couple of times, binerdle has used one of the nerdle solutions.
Yesterday, I had it narrowed down to the same two possibilities as the previous day's binerdle. I missed the 50-50 for binerdle, so for nerdle, I thought I'd choose the same solution as binerdle, but it turned out to be the other choice.
Back to a 3 today.
