I can see where you are coming from. We had a similar problem in one company I worked for. Engineer said it was fine, chief pilot saying if it was not in our book, then snag it. I got fed up with being caught in the middle, eventually I filled an ASR which got the matter sorted. All pilots were issued with clear instructions from the ops director and manuals amended. That was the big airline solution.
Just out of curiosity, did anyone ever reject a take-off, and I presume a number of pilots did continue with the take off and noted an alleged exceedance in engine parameters. So I wonder how seriously the flight crews actually took the issue. I think being a Chief Pilot in your firm could be fun and entertaining
