(Does that relate to the 2 numbers I told you that appear? "8625/12500")
The WUs of each project are assigned a point value, depending on how much time Stanford estimates they will require. Each time you finish a WU, you and your team are awarded the points.
The numbers you refer to are are the "steps" required to complete the WU. Your computer has completed 8625 out of 12500 required steps. That WU is 69% complete.
(8625 / 12500 = 0.69)
