Hi there,

I have a huge data set (10 units and 5 years data set) that contains for each unit an indicator whether a unit is fully or partially operational or zero if not in operation. I am interested to know the number of blocks (a block is defined as a sequence of fully or partially operational days) and the average operational days within a year.

For the sample data below, Unit 1 has 2 blocks and Unit 2 has 3 blocks. Average Operational days for Unit 1 is (1.5+1.8)/2 = 1.65 days

Is this doable in Excel or Excel VBA ?

Any help in this is much appreciated, thanks in advance.

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.
Try this:

Same basic idea as kweaver, but the formula I use to count the number of blocks doesn't assume that there is exactly one "1" per block.

Yes it works on the sample data but the case I have it could be a longer sequence of ones then followed by either a value between (0.1 and 0.9) or zero.

I apologize for the confusion :( I have corrected the sample data to account for such cases)

And, what would you expect the averages to be in each case of your new sample?

Same basic idea as kweaver, but the formula I use to count the number of blocks doesn't assume that there is exactly one "1" per block.


Thank you Eric, this works perfectly much appreciated :)
