The work behind it

No source we can reach publishes a hashrate for Primecoin.

What a regulator has said

No SEC/CFTC determination — unclassified.

Reported as the regulator's position, not ours. Assets nobody has ruled on are left unclassified rather than sorted by our own guess.

Why this ranking is shorter than the others

An asset counts once. Wrapped coins, staked derivatives and stablecoins are claims on something already in the list, so they are listed separately rather than added to the total. That's why Primecoin sits at #173 here versus #1553 elsewhere — the 1380 positions between them are claims we don't count as separate assets. The methodology sets out both rules, and the counting rule argues for them.
