How far back does it go, and what survives at that depth?
The span of the historical record, and which fields survive at each depth of it. The two are separate questions. Results, serve statistics and point sequences do not reach equally far back.
Why it separates providers
A backtest is bounded by the shallowest field it needs. The deepest year on the marketing page tells you nothing about that. The free open datasets this field long relied on are no longer available.
The test you can run
Ask for a match from each decade and diff the fields you get back. Find the year each field you depend on actually starts. A single advertised span will not tell you that.

The other criteria
| # | Criterion | The question it answers |
|---|---|---|
| 01 | Latency | How quickly does a scoring event reach your code? |
| 02 | Completeness | What share of matches actually carry every point? |
| 03 | Tour coverage | Which tours are in scope, and are they equally served? |
| 04 | Point-by-point | Is there a real per-point record, and does it say where it came from? |
| 05 | Streaming | Can you subscribe instead of poll, and how far does it fan out? |
| 06 | Free tier | Can you evaluate it properly before paying, without a card? |
| 08 | Spec and SDKs | Is the contract machine-readable, and is it kept honest? |
