# Model Descriptions

The **Power Meter** is a physiology tool - for monitoring training intensity, measuring training load and tracking fitness development by measuring Power (Watts) and providing feedback once-a-second or once-per-stroke.

The **Power Meter w/ High Speed Data** builds on the physiology focused features of the **Power Meter** and adds biomechanics/technique focused features in the form of additional real-time metrics and the introduction of High Speed Data. The features of the **Power Meter w/ High Speed Data** are a superset of those found in the **Power Meter**.

We encourage those who aren't sport scientists or researchers; those who don't have access to a sport scientist or a highly analytical coach, or those who aren't part of a national team (where access to sport science expertise is a safe assumption and team boat paddling is common) to opt for the **Power Meter** as the additional features of the **Power Meter w/ High Speed Data** may not be effectively utilized in all cases.

On the flip-side, if you have access to a sport scientist (particularly if they have a background in biomechanics) and/or team boat paddling is common (where detailed stroke-timing between athletes may be investigated) then we strongly recommend opting for the **Power Meter w/ High Speed Data**.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://support.onegiantleap.co.nz/2.1/general/model-descriptions.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
