Yup.

Average use per day, then, is the number minutes used in the week divided by the number of days, so:

Mouse: 1140/7 = 162.86 minutes, or 2 hrs 42.86 mins average per day

Keyboard: 691/7 = 98.71 minutes, or 1 hour 38.71 average per day

Thanks Steve. Chris also did it, and you match. I was initially using the number of 1180 mouse hours from August 1 to August 10th, I got 118 mouse hours in those 10 days, and then I divided by 9 and got 19. Now I see where I went wrong, first the 10 days was too much for a week, I needed to stop at the 7th. Second, I think I had the 19 right but I was thinking it was hours, not minutes and I knew if overall usage averaged to 7 hrs a day, mouse would not be able to be 19. Then after that, my logic failed.

Thanks again
