"The benefit of using M to store additional information instead of a regular number attribute field is that you can then store for example a line string that represents a path as a single geometry with each observation point and time difference between actual and expected of arrival along the path and not have to explode related information about each point in that path in another table."

"of" needs to be removed

Also, this is a run-on sentence. It would be far more clear/readable to break it up into two or more sentences. The judicious use of commas would also help with clarity.
