Scorecards - Historical Tracking

I was reading through the "Configure Account Scorecard History" GainsightGo article and I had couple questions.

• How can I see if my snapshot will be every week or month?
• Where is this stored in the usage?
• Is there a configuration connection step in SFDC that I was supposed to perform?

That article lead to another GainsightGo article, "Configure Account Scorecards". Under the Validity Period Example header, there's a snapshot of a group of scorecard measures. The snapshot shows a color for each of the measures and each color is accompanied with a score (#) and an arrow indicating if it's up or down from last time. Is there a way I can enable the score (#)? I have the color and the arrow, but no score (#).
