Stores like yours
Your store set beside stores of a similar shape and size, on the measures that decide a month. You see where you sit. It is a bearing, not a league table, and it names no other store.
Benchmarks
How you compare with stores like yours
Your own numbers tell you what changed. Stores like yours tell you whether it was you or the market.
What is inside
The floor the comparison stands on
A comparison appears once five or more stores are pooled behind it, and every figure you read is built from that pool rather than from any single store in it. Where the pool is thin, the comparison waits until it is not.
