Phase Confidence Score: How Much Should You Trust a Label?
Every county label on the radar arrives with a confidence score from 0 to 100. The number is easy to misread as a probability of future success, which it is not. It measures how comfortably the price readings sit within the rules for the assigned phase. This guide explains how to use it sensibly.
- The score reflects how cleanly a county's price readings fit its phase rules, not the odds of any outcome.
- Lower scores flag counties near a boundary where the label could change with the next monthly update.
- A high score still depends on the underlying price series, which may come from a wider area.
- Reading the score alongside the label and its history gives a fuller picture than either alone.
What the number actually measures
Imagine a county tagged contraction because prices are falling and sit well below an earlier high. If both readings are far inside the rule boundaries, the score is high. If the year-over-year decline is barely negative and the drawdown only just qualifies, the score is lower. The number therefore describes distance from the edge of a category, a bit like how deep inside a state border a town sits.
What it does not measure
The score says nothing about whether the county is a good place to buy, whether prices will move in a favorable direction, or whether the data behind it are high quality. It is a classification-fit indicator, not a quality grade. Reading it as a safety rating would be a serious misuse, and no outcome can be inferred from it.
Using low scores as a prompt
When a score is modest, treat the label as provisional. Look at the preceding few months to see whether the county has been oscillating between two labels. Borderline counties are interesting because they are often in transition, but they are also the likeliest to flip next update. A cautious reader waits for confirmation rather than leaning heavily on one reading.
Using high scores wisely
A strong score means the label is stable with respect to the rules, so the description of price behavior is clear. That is useful when scanning many counties: you can focus first on those whose categories are unambiguous. Still, a clearly classified county may have an index inherited from a metro or state series, so cleanly labeled does not equal locally precise.
Pairing the score with history
The best habit is to read three things together: the phase, the score and the direction of recent change. A rising score within the same label suggests the county is moving deeper into that phase. A falling score suggests drift toward a boundary. These small trends tell you more than a single snapshot ever could.
Phase Confidence Score: How Much Should You Trust a Label?: questions
Is a higher confidence score better?
Higher only means the readings sit comfortably within the phase's rules. It does not mean the county is a better place to buy or that prices will behave favorably. It is about label stability, not quality.
What score counts as low?
There is no official cutoff, but scores noticeably below the middle indicate the county sits near a boundary. Those labels are more likely to change after a monthly refresh and deserve extra scrutiny.
Does the score predict the next phase?
No. It reveals how close the current readings are to a rule boundary, which can hint at instability, but it does not forecast which way prices will go or which label comes next.
Can the score be high if the data are borrowed?
Yes. The score assesses fit to rules, not geographic precision. A county using a metro or state index can score high while its local streets behave differently, so check the price source too.
