Looks like a really cool product. Are you thinking of moving to android? Don't mean to nit pick but you are mixing up accuracy and precision. If your standard of deviation is 20% lower, then you are more precise then professional tailors. Accuracy denotes some distance from some "true" value. Accuracy != Precision

Definitely planning on Android (but not for a few months).
You're definitely right about precision vs. accuracy. The phrase never polled as well. Maybe if we'd run our surveys in the statistics department it would have been different. :-)
