Just wondered how many of you folks have a calendar specifically used for plotting trends in the industry?

For example, do you write down your daily / weekly / monthly sales and traffic figures?

Do you keep a note of 'low' yielding time frames so you can plot 'patterns' in times when sales are higher or lower than usual?

I started doing this a few months back on a daily basis and i have to say, some of the information ive accumulated shows some pretty good trends.

Just wondered if anyone else did something like this with their business?

Regards,
