Per property, the measured values inside this excerpt. The share refers to the 10,062 entries of the excerpt, not to the registry.

The same excerpt through the interface

curl -s "https://api.tracevero.com/v1/eintraege?art=mcp_server&roh_transportarten=stdio&grenze=200"

The command carries exactly the condition of this page. 10,062 entries at 200 each are 51 requests; the total is in the X-Gesamt header.
