The bonus hour amount will be a certain percentage (that you specify here) of the hours record's duration.
Fixed amount
Every hours record gets the same number of bonus hours regardless of the hours record's duration.
Percentage of hours beyond a certain length
Similar to Percentage of hours above, but the credited amount is a percentage of the hours record's duration beyond a certain amount. Use this for things like overtime, where they get a bonus for the hours beyond eight per day.
