I think that you will make your life a lot easier if you just accept that you are talking about the CL601 ONLY
My one interaction with Bombardier was related to the CRJ, due to a lack of computerised software, they had a hard time validating ANY takeoff weights, so I would be extremely surprised if they can give you a proper answer related to all engine performance.
Good Luck and make mine a Guinness
