I pop in and out of this forum sometimes as to learn from other webmasters who are making use of Adsense.

There are so many posts on the forum every second day saying "Today is sooo bad, I can't believe it!".

Isn't looking at on-going daily stats just a stupid waste of time?

This should be a month-to-month project where tweaks to layouts etc should be tested over thousands of visitors across different days. There's always going to be variations in income. You should compare positions, channels, pages and sites on their average relative performance instead of looking at how many dollars have arrived today.

Opinions?
