Do you want to divide by 3.8, instead of by 4?

I have a monthly scorecard where I have four employees and how many
pieces of work they completed in that month. I then get an average of
how many pieces are done a month by dividing the total amount by 4.
It has been brought to my attention one of the four employees only
does this part of the process 80% of the time. How do I get an
accurate average now knowing that the fourth employee is only doing
this process 80 % of the time and not a 100 % like the others. If I
do the average as I have been, the fourth employee with 80% is bring
the average down.
