I understand your question. I think it would be a difficult thing to do because we all retire at different ranks. I retired as a constable, so I would get the lowest. If I were a staff sergeant, I would be making more money.
I have a good friend who's a staff sergeant in the RCMP. We started working on the same day. He is still working, but at the end of 32 years, if he had retired the same day as I did, he would have had a substantially bigger pension than I have, because he would have made more money as a staff sergeant than I made as a constable. Therefore, his 64% would be a lot higher than my 64% in the same number of years, because we retired at different ranks. The higher the rank, the more money you make.
If I went on a disability pension after 32 years, and he went the same day after 32 years as a staff sergeant, he would make more money than I would. His pension would be higher because he made a higher salary, so his five-year average would be higher. I might be able to tell you what I'm going to get, but I wouldn't be getting what he's getting, because he has acquired a higher rank. An inspector would get a lot more money, and so on up the line.
