> Of 129 active groups, the top five posted 3,027 of the 7,655 claims (40%). After them, the field fragments quickly.

Does it?

The 4th group accounted for 5.0%, 5th was 4.5%, 6th was 3.4% and 10th was 2.5%, I think it doesn't fragment particularly any more quickly after the top 5 than within the top 5.

Is this LLM analysis?
