I don't. I roughly measure the time I use on a problem, but that is mainly to not loose myself in details. But otherwise I deliver when its done

Hell no. Sometimes I reflect without typing anything for minutes. This time is essential to focus on the important parts. I also make pauses and get a coffee whenever I like.

Life isn't just work, I don't need to tune my productivity. I think my boss is happy I deliver reliably... more or less.

Context switches are deadly for productivity though, on that I agree. This is why I vastly prefer asynchronous communication. Yes, you can probably answer that mail tomorrow...

From a dashboard I expect that I can share its info with others working on a problem to sync our work. Don't know if that helps.
