Calculate additional values based on results of Pivot Table

I am trying to make a summary of some cleaning results in Excel with the aid of a Pivot Table, but I am experiencing some troubles wrapping it all up. I have the following data:

Cleaning 1    Location 1    Result 1
Cleaning 1    Location 2    Result 2
Cleaning 1    Location 3    Result 3
Cleaning 2    Location 1    Result 4
Cleaning 2    Location 2    Result 5
Cleaning 2    Location 3    Result 6
Cleaning 3    Location 1    Result 7
Cleaning 3    Location 2    Result 8
Cleaning 3    Location 3    Result 9

Currently, I have a Pivot Table containing the average and standard deviation of each location, as well as the average and standard deviation of all the results combined. I would also like to have average + 3 * standard deviationDaar for each location, as well as for all the results combined.

The info I find handles calculating additional paramaters based on the ORIGINAL columns of the data, but not combining RESULTING data in the Pivot Table. Any help?

What I have tried so far:

GETPIVOTDATA is a nice formula, but it does not work ideally for me since I will be using the filter options of the pivot table. Also, it does not seems to work for the total.
