Calculating percentage in beast mode based on count

Hi, I have a dataset that looks like this:

Network     Hour     Date     Avails
A           1        1/1      2
A           2        1/2      4
B           1        1/1      6
B           2        1/2      8
C           1        1/1      10
C           2        1/2      12
C           2        1/2      12

The number of avails is the same for every row that has the same network, hour, and date. I need to write a beast mode that calculates the number of different rows that have the same network, hour, and date, and divide that count by the number of avails (not summed). So for the last two rows, the calculation would be 2 / 12. This needs to be in beast mode since the calculation will change depending on certain filters.

Thank you!

The numerator seems like it will be a straight count.

For the denominator, you want an average of the Avails fixed by your distinct grouping.

count(Network)/(AVG(Avails) FIXED(By Network,Hour, Date))

@jrtomici so are you saying your resulting beastmode on that data would calculate the below.

@DavidChurchman I think this is the right track, but it's not perfect.

The second to last row (A, 3, M) should be 0.33 since it's one row with that Network/Hour/Date combo and 3 avails.

@jrtomici

Hard to say what's going on. It looks like you added a few rows to your example data. Could you post a screen grab of the raw example dataset, too?

jrtomici

@DavidChurchman sorry, I did add some rows just to test your formula since it wasn't working on my actual dataset.

I now realize that it's working as intended!! Sorry. I still don't know why it won't work with my dataset but I will look into it.

DavidChurchman

There are two A/3/M rows, so 2/3=.67 is correct, right?

jrtomici

@DavidChurchman yes, that is correct, my apologies. Formula seems to work with the test dataset but not the actual so I will need to do some digging. Thank you!
