Add views by week rather than last 7 days.
I assess training performance by a cycle of Mon-Sun rather than just the last 7 days. Would prefer to see how I've done since Monday rather than the last 7 days. The high mileages of Sat & Sun block the ability to see performance since Mon. Looks like a number of people are asking for the same default view.
