Scale Points 10-to-20

I need help updating an existing points framework so that everything now runs on a 20-point scale instead of a 10-point one. Wherever the number of available points is referenced—calculations, stored values, on-screen labels, export files—those references must adjust seamlessly to the new range, including any rounding logic so historical data still makes sense.

The underlying codebase is already in production; nothing else in the workflow should break once this change is deployed. I will provide:

• A quick walk-through of the current points logic
• Access to the repository (JavaScript/Node on the back end, React front end)
• Sample data for regression testing

Deliverable: a merge-ready pull request with clear comments, updated unit tests, and a short change log explaining the key edits. If something in the code or database schema makes a straight conversion risky, flag it and suggest the safest workaround before we go live.
