Understand FIT ingest warnings

When you select a FIT folder for calibration, TRIPS checks the folder before full processing begins.

The warnings are meant to answer a practical question:

Is this FIT folder likely to be manageable in this browser session?

TRIPS looks at:

TRIPS then shows a risk level before you continue ingest:

Low: this folder size usually ingests successfully
Medium: ingest may take a while and may not restore fully after refresh
High: ingest may be slow or may exceed browser memory or local storage limits

How to decide what to do

Continue when the folder is representative and you intentionally want to try it.
Cancel when the selection is obviously too broad or messy for a first pass.
Start smaller when you mainly want a useful calibration rather than the biggest possible dataset.

Continue if you intentionally want to try the full folder.
If the browser becomes slow or unstable, try a smaller subset of activities.
If you mainly want calibration from recent or representative outings, start with that subset first.

TRIPS processes FIT calibration files in the browser and stores a derived local snapshot for the current device and browser.

It is not a cloud-synced upload workflow.

That means very large or messy FIT selections can push browser memory or local storage limits.

A high-risk warning does not automatically mean your files are bad.

It means the selection may be too large or too heavy for a smooth in-browser ingest session.

Treat the warning as a workflow decision, not as a verdict on your data quality.

The best next step is often to use a smaller but more representative folder first.
