I have a calculated metric in the form of a timelion script:

> {count today / [(count offset7days/3) + (count offset14days/3) + (count offset21days/3)]} \* 100

this shows me the % of count this week over average of last 3 weeks.

how do i put this logic into a Watcher script? I want alerts to be coming in every time the percentage drops below 75%
