Someone else mentioned that it looks like competitive gamers and the like use that site to train their skills, which makes sense considering my results; the two I got above average scores in were things I doubt those types would be interested in retrying over and over.

I thought having a touch screen would be a huge advantage over using a mouse like I did too. It's hardly perfect!

Mostly I just wanted to measure what I was feeling somehow, though it'd only really mean anything if I compared to my own performance when in a better mental state rather than some faceless crowd who are likely either 'cheating' or actively trying over and over to attain ideal results.
