Response time

Not something new, but thought I would share it. This is something we implemented on my website to show the response time and be accurate. Well, the context changed a bit, but still the same idea. The donut chart is indeed dynamic, meaning that it's not a static image. It's the FF Chartwell font for web, works like a charm for retina and uber easy to manipulate.

Responding to emails as a one-man-show have been difficult, so I think being honest about the response time is the very least I can do. What do you guys do?
