Uptime Monitor stats don't add up

Hello,

The issue is with the Uptime Monitor. I see that the stats don't match the data below. For example it says my website has been down for a total of more than 2 hours. When you look at the times it went down it adds up to 34. If I change the date range to Month, it gets close to what it really is. If I select week for the date range it's way off. I've had it active for less than a week.

This is a great plugin, and I've been looking at some services like this one. Knowing you guys added this to your long list of tools is great! Any plans on expanding on it? Like getting an email when the website goes down rather than when it goes back up?

Best regards,

Paul
