I've updated the tool to also print statistics on how many arguments there are for the places where it can perform the analysis. 

I also added statistics for how long variable names it finds. I'm pretty sure almost all places with the length 1 or 2 for variable names passed would be better if they had been synchronized. Those places are also an argument for my suggestion I think, because if you gain something to synchronize then that will make you less likely to shorten variable names down to 1 or 2 characters to get brevity. Maybe...

If you exclude calls to functions with just one argument (not parameters) then the hit percentage on the code base at work drops from ~36% to ~31%. Not a big difference overall.

I've updated the gist: https://gist.github.com/boxed/610b2ba73066c96e9781aed7c0c0b25c <https://gist.github.com/boxed/610b2ba73066c96e9781aed7c0c0b25c>
