These are the operational considerations that I was referring to.
The point regarding margins is the real one IMHO.
If someone was to post with some data describing the long term effects of constant overweight ops, and quantifying how structural safety margins are eroded over time, we could form a reasoned opinion about what is acceptable, or not, to each of us.
Just saying "don't do it", and making uninformed forecasts of how an insurance company will treat any subsequent claim would seem to be unhelpful.
