## How to choose

- Batch size per write: Check the largest batch of cells or records one write can carry, since many small calls are slower and use up an agent's rate allowance.
- Formulas that recalculate: Check that a formula written through the API is calculated by the table, not stored as text, since a value that never recalculates goes stale.
- Read-after-write consistency: Check whether a read straight after a write returns the new values, since an agent that appends rows and then reads them back needs the table to be current.
- Change notifications for edits: Check whether changes to rows, cells or formulas raise an event the agent can receive, so it reacts to an edit without polling the whole workbook.

- How the benchmark tests this category: The same workbook of one thousand rows in each listing. The same tasks run through its API (read a range, append rows, update cells in a batch, add a formula column, filter records). We check limits, consistency after writes and change notifications. In this run listings are graded from public evidence against the published checklist.
