I think anwser siezure ratio & call success ratio might be same. Please carify me , if i am wrong.
Answer Bid ratio = (Number_of_answered_calls/Number_of_Bids) * 100
Answer Seizure ratio = (Number_of_answered_calls/Number_of_siezure) * 100
where
Bids = Call attempts
Siezures = Attempts which got/sieze the connections
Answered = Attempts which got the connections and anwsered.
