It's OK that you were aware of the limitations by not using the circular saw that's designed to be used with the track, and for your specific purpose then that's fine, but I don't think it's best to give advice to confuse others that might not be aware of those limitations.Certainly - I did know its limitations, but I wanted the saw for other purposes.
There'll be a difference between where the blade sits and the nylon guide ...
No, it sits in the same place. The guide has to be trimmed to suit the blade.
Even the manufacturer says that the CCS isn't compatible with the track...........but who am I to argue with the people that designed and manufactured it.......?!?
