Yeah it will be interesting. I can see two possible scenarios happening.
Sid will either TIE his next home game and CT the third game OR
he will CT the second game and CT the third game... fairly obvious. But let's break it down to who has how much enthusiasm.
I'm going to assume we are both on the same enthusiasm (given that we have TIE'd pretty much every game this season). I'll set the arbitrary number to 10.
Scenario 1: Sid does TIE, CT
He will go into Saturday with 9.451 ent, I will have 8.126. If he TIEs and i TIE, by Sunday he will have 11.385, and I will have 10.835 - approx 0.5 difference. Not ground shattering by any means.
Scenario 2: Sid does CT, CT
He will go into Saturday with 9.451 ent, I will have 8.126. If he CTs and I TIE, by Sunday he will have 8.941 and I will have 10.835. Huge swing in my favour (almost a difference of 2 enthu)
My guess is he will go with Scenario 1. If he wins, he has a slight advantage in enthu going into sunday,
That is assuming I will TIE on Saturday though.
