So 22 - 5 = 17 or the majority.... I think thats right. I've shown my workings out so you can check.
Pitts extra, I'v no complaint about the math but don't concurr that the majority can be described as zero yeild.
Off topic, getting a response from the airwing is a job well done, having formally asked a force in another country for details of flights during a natural disaster, for the purposes of research, I was eventually told that all operations that day had a law enforcement role and so they were unable to provide details of any flights.
