Help working out daily productivity

[RossB1010]

Hi

I'm trying to work out how to calculate productivity for a team based on the number of days worked this month so far. Normally it would be a very straight forward total/av days.
However of the two people in the team, one has worked 8 days this month and the other has worked 5.

my question is what calculation should be done to work out the average overall taking into account the different amounts of days that the people have worked?

Thanks in advance

Ross

Wouldnt it just be output divided by total days worked by the team or am i missing something?
