I don't think this is a bad idea at all. Micro-work should be tracked for both the worker and client's sake. Paying hourly is highly inefficient as we all know it's very difficult to work every second of an hour. So if something could more precisely track how often you work during an hour it may encourage you to work less not more as you'll be able to see when you start to taper off; the longer you work the less efficient you may become.
