Understand Precision
Suppose you found a reliable sign — can you always trust it?
That’s what precision is about:
How often does a migraine really follow the sign?
High precision means you rarely get a false alarm.
And that’s valuable. If you’ve found a sign that reliably predicts an attack — hold onto it.
But be aware: signs with high precision often have low sensitivity. They don’t show up often — so you may miss many attacks that don’t follow this pattern.
We’re working on algorithms to improve this balance. But we’re not there yet.
For now, precision is powerful — and limited. It’s one piece of the puzzle.
