His claim was about the age at which potty training was successfully completed. Your chart is about the age at which potty training started. They’re not comparable unless you provide some additional data about how long the training takes.
4 & 5 from anecdotal data - friends/relatives in day care. Those are outliers but they do fit the trend.
Around 6 months is extremely common in places which use “elimination communication.” The article I linked described this.
I don’t have children but consider myself both an academic and personal stakeholder - ie, I’ve changed a fair amount of diapers and I have taught parents how to parent to reasonable success.
I personally was potty trained at 4 - as in, I have episodic memory of getting Pokémon stickers as a reward for shitting.
There’s been severe regression related to COVID too. The school district I worked at had to send out reminders to parents that potty training was a pre-requisite for preschool - and many parents put it off until the need to send the kid to school forces the issue.
