That 200-500 years has consequences beyond archaeology. People studying that geographical area use the established Egyptian timeline as a control when dating their own work. Dating the eruption of Thera is one example. If the Egyptian timeline is off by so much as a year, volcanologists' work is also inaccurate.
There's more at stake here than just bragging rights. Other people's life's work depends on them getting it right. In that context, when a year can throw off decades of careful research, 200-500 years isn't a itty bittie little mistake. It's huge.
