I didn’t understand why he earned one hour one day and two the next, was it the time he worked that day?
Maybe this is a language problem
Wouldn’t it be better to score based on % of the estimated time for the task to be completed?
example, if the expected time was 2 hours in 3 hours, he would not gain a point
now if the expected time is 5 hours from 7, you would no longer earn the points
Did you manage to find any solution? since 30 days have passed
