why would the spreadsheet make you suspicious? it isn't something he thought of and whipped up since he was given his role last night. it's just a wolf strategy that he is subjecting us to with our knowledge.
It's not at all the spreadsheet that makes us nervous/suspicious/whatever; if it's done well, it's a fantastic idea and I'm surprised Destil hasn't written a program like this already. It's not even his claim that he's got one and he's going to be voting for people using it, though that could lead to some amazing cop outs later on ("I vote for gahitsu! She's totally suspicious, according to my calculations, but I can't really talk about it or explain it but I've got the numbers and I'm voting yes!").
It's just that, if you think you have a great system, and have identified some fantastic patterns that makes someone more or less likely to be a disgusting Wolfpire, then you should keep it to yourself (fake edit: as Nicka says, "oon as it is explained it starts to lose value because people can game it"). An idea like this should probably be kept to yourself. And to further clarify:
...basically, there are certain factors that I'm convinced strongly indicate someone's on a non-innocent team. Unless and until one of those giveaway factors appears, I vote for people who contribute the most to certain voting and behavioral patterns that I feel reinforce a negative game atmosphere. However, the corrective impact of this voting methodology is blunted when the affected individuals can't tell whether I'm voting for them because I think they're evil or because I think want them to stop reinforcing negative trends... but letting people know why I'm voting for someone at any given moment would reveal the "giveaway factors" I'm on the lookout for.
I couldn't decide whether to be predictable or not. Thus: the vote.
Look, if a dude or a dudette is leaning towards some negative trends, but you don't think they're Mafia, don't vote scare them out of it. Call them out on their bullshit, explain why their bullshit stinks, and watch 'em after. If you think they're blowing bullshit because they're mafiosos, call them out on their bullshit and then vote for them.
I can understand why someone would make something like this. I can almost see why someone would claim to have it. I can't understand why someone would offer to put it up for public consumption, for any good reason. Again, probably the most positive thing I can claim is that this is a thought experiment and he's waiting to see who jumps on this like this is a good idea.
