I'm yet to find a GA company that's too fussy on weights - either pilot weight or Max TO Weight..........
How often has a weight and balance been adjusted to show absolutely min legal fuel plus reserves, whilst there has been quite a bit more fuel "For Mum" in the tanks? How often has the pilots weight been accurate and include his flight bag? Is all emergency equipment included in the empty weight?
And that does not mean I condone overloading - I don't. Simply a fact of GA life.
