Email Alert for a Scorecard

All,

I want to create email alerts on a score card or Gauge. I will be using Power Query in Excel file to call PowerBI API. 

My question is in PowerBI can any formula work on the score card? 
I have two columns I am using to find the difference. I will be putting this on score card will this work? 

Also what if I have an alert for when the score card reaches 0. If it jumps to 0 and then 10 within minutes will it still alert me?
