Contact coverage rate report(very complex, combine analysis)

Question

Hi experts,
we have a KPI to measure the contact coverage base on segmentation.
the business scenario is as following:
1. We have 4 segments for tcontact, A, B, C, D. it is the custom filed in contact object;
2. my contact: if I am in the contact team, even I am no the owner of the contact, the contact is also mine;
3. My visited contact: the contact associated with activity which the owner is me;
The seg A contact coverage rate = # of my visited contact with seg A / # of my contact with Seg A;
The difficulty is it is in different report subject area. my contact should be used "Contact Tem", my visited contact should be used "Activity history";
Now I can use combine analysis to run out # of my contacts by count(contact id) in contact team; subject area and the # of my visited contacts by(count(distict(contact id))) in activity subject area. the question is how I can calculate the rate, it is on different row same column;
Please help;
