Please allow score cards to be calculated to a decimal as WSJF scoring requires this. From @Andrew Scott
For CTM we added custom fields to log a decimal score in both the features and master features/epics...and then created a custom WSJF score card. If score cards went to the decimal, we could have just used the score card.
