Debunking the 3 bite "wow"

So a while ago Thomas Keller is allegedly reputed to have said that palate fatigue occurs after 3 bites. If Mr Keller's lawyers are reading, the phrase "allegedly reputed" nullifies your libel suit.
In any case this is a quote that many chefs have used subsequently to justify microscopic portions.
Frankly my friends, it's utter nonsense.

Palate fatigue is not simply a linear function of portion size, how about richness, salinity, texture.
Let's all stop kidding each other.
Bing.....(with sound effects)

For the record Chef Keller is someone I deeply respect and regret not working for.
Just keeping it real.
Thoughts anyone ?
