My site is making some huge swings up and down but I too know this is a good sign and I'm not panicing at all. I'm adding content as often as I can and leaving John to do his work. So I'm gonna let John's service run for a few months and hold on for the ride to the top of the G tree!
One thing I will add, I don't recall having such confidence in a service before, but for some reason, with this service, I've not even set a reminder in my phone to remind me to cancel the day before it's due to renew!
