I wasn't going to change it as we stated in the beginning that the Championship was going to be 8 events. I suppose I was just blindly following the "half plus 1" rule (13/2 + 1 = 7.5 so rounded up to 8 anyway) which I guess with an odd number of events we could just do "half". I think it is too late to change the formula now.
For full disclosure though, I am a little biased now because after the last even where I stated Ben had claimed 1st in Modified and he can't be beat, I figured out that mathematically I still actually have a chance get 1st place back from him. It is an extreme long shot but it does exist.
So based on that bombshell, I will entertain others' opinions on the matter. It's a sticky situation because if you benefit from a change you will likely want it and if it hurts you you probably don't.
