He’s done an update on his podcast recently. Now some parents are using his data to intentionally hold their Children back a year to give them an academic advantage. Enough to start skewing the data.
Edit - I don’t think gladwell came up with this idea but he did make it more mainstream.

It would be easy to enough to adjust for birth year. Instead of just birth month, it would be number of months older than the minimum.
For instance, someone who turns 17 on Sep 1 of their senior year (12th grade) would be considered "0 months" old. The typical range would be 0-12 months if everyone was born in that year, but someone who was held back and turned 18 two months before their senior year started would be "14 months". Your range might be as much as 0-24 instead of 0-12.

I listened to it a while ago but that sounds similar to what he ended up doing.

He didn't, in the podcast he talks about the Canadian researcher's wife who noticed it.
