Publishing behaviour
The catalogue’s attention is unevenly distributed. The single most-rated app holds 30% of the 440 ratings observed across 64 loaded listings, and the top three hold 57%. That is a portfolio led by a small flagship set rather than an even bench.
Roughly 13 apps account for about 90% of the observed ratings; the rest form a long, light tail. We read that as a strategy signal, not a cadence number: the publisher lists the most apps in Utilities, yet earns the most ratings in Education — volume and audience sit in different places.
