"How big this risk actually is remains debatable."
No..it's not debatable. We've dignified this lunatic argument long enough. The largest aviation governing body on the planet has already ruled against it. End of story.
If my 45 years of flying (35 years of it in check and training) given my first hand exposure to assessing pilots of all experience levels: In 99.99% of the cases, if comparing a pilot with 5000 hours of high quality flight time to any sprout with less than 200 hours, the inescapable conclusion is that the experienced pilot is safer and the one I would want in a cockpit when the sh*t hits the fan...and in 100% of cases, the 200 hour pilot is cheaper, riskier, and less safe.
Prima facie.
