I have a lot of doubt over the graph just based on how they average the results. You’re bound to get people guessing super high or super low, which would skew if they were just getting the mean.

I use Dropbox too. Though I have to admit, when running code you sometimes have to pause sync otherwise it interferes with code execution. But definitely worth the peace of mind. Sometimes you don’t want to commit stuff until you’re sure that it works.
