You've made Ed Tufte cry... The concept is cool, but the display is terrible. Black and white, seriously? There is no organization, no drawing attention to the relevant data (is anything recently changed? Out of the usual range?). Just a bunch of data thrown at the screen.
I do the NYT crossword every day, so I have a good idea of how long it should take. For instance, Monday should not take me longer than about 6 minutes. Thursday takes 30 minutes, Sunday takes 55 minutes. If I'm much above that, it means I'm not all there -- time to go for a brisk walk to get the old brain going.
Don't give up, but you got some ways to go.
