Averaging those rows unweighted is how a &quot;most expensive queries&quot; report quietly gets the ranking wrong on a busy instance. <code>sys.query_store_runtime_stats</code> is the catalog view holding that interval-level detail, and joined correctly to plan, query, and query text — with a weighted rollup across execution counts — it produces the resource-consumption ranking a DBA actually wants.</p>
