Calculate percent from query fields?

We have a number of query fields to track the total number of shots, shots in progress, shots complete, etc… I cannot find a way to use these query fields in a calculation in order to calculate the percent. This must be getting done internally somewhere because pie charts are generated. Is there a way for me to access the percentage value?

We’d love to see this too! Eg. What percentage of Shots are complete in a sequence, rather than a number.
