It seems they based it on a GDP PPP table and growth rates expected for 2019, extrapolating them to 2024 (2019, 2020, 2021, 2022, 2023 years)

Japan (1% growth) would be 5.875u, clearly behind China (34.2982u), USA (22.9573u) and India (14.9486u).

**Indonesia **is the clearest error even considering that source. It had a 5.2% growth rate, which would put it in 2023 almost on par with Germany (4.5372u) and Russia (4.5578u), while Indonesia would be 4.4968u. The 4.5-4.6u range, but Indonesia was clearly on the lower end.

A while behind would be Brazil with 2.1% growth, on 3.7390u.

UK would be 3.22683u, France would be in 3.1574u, Mexico would be in 2.7823u.

It seems compared to their estimations China fell a bit shorter than expected (covid), US did much better than expected (expectations were low), India didnt grow as much as expected (huge expectations).

Japan did better than expected (expectations were low), Germany and Russia did better than expected, Indonesia had too big expectations.

And Brazil, UK and France did all better than expected.
