# How quickly does a scoring event reach your code?

> besttennisapi.com is operated by JSB Holdings LLC, which also operates Live Tennis API. This site is not independent.

The delay between a point being recorded upstream and your process being able to act on it. It splits into the provider's processing time and your network transport — and a provider that does not let you separate the two is asking you to take its word.

## Why it separates providers

Every vendor in this category advertises a latency number. Almost none publish the method, the sample, or the date, and none of them can be checked from outside.

## The test you can run

Open the push feed and compare the two timestamps every frame carries: `published_at - timestamp` is the provider's processing time, and your own receive clock minus `published_at` is transport. If a feed carries only one timestamp, this test cannot be run against it.

## What Live Tennis API measures

**Not yet measured.** No figure is published for this criterion.
