It's either something with me, or the wording feels off. When I landed on the page, I caught the graph with the corner of my eye, I assumed it is a graph of productivity and started reading from the top. The context of the message feels just not on the right level - I assume that most visitors will immediately grok what this graph is about, and instead of presenting more context to - ex. how you measure it, how to get one for yourself, what is the quantifiable bit behind it or where it falls short - I get a vague message which explains to me when and how are time-series applicable to productivity measurement - which, perhaps mistakenly, feels pretty obvious to me. Didn't mean to sound harsh, I might actually try your service, but this message just didn't cut it for me.
