Sorry Nad this is not acceptable, if you see **big problems** specially given how friendly Paul is and how hard he works in this group, you **must** accept resistance to your criticism. This is a part of analytical discourse to hash out issues and problems, obviously sometimes it might even get heated but that is what engineers do all the time and it is not personal.

If you hold others accountable to their analysis and they have the right to reciprocate, responses should be accordingly rather than one way jab from grammar use to thermodynamics.
