This is a two part idea:
1. We need a true NPS calculation. The way Survey's does this currently, it takes the average of responses across a Customer and gives you a 0-10 score. However, NPS should actually be %Promoters - %Detractors. "The current NPS 0-10 score is misleading" (direct quote from a customer).
2. For the Widget in the Summary Section, it would be nice if we could add a time option for it. Allow a customer to choose if they want the true NPS calculation (which we create from above request) to represent ALL Time, Last 30/60/90/180/365 days, etc. This way, they can truly reflect what they consider to be the NPS of the account.
