Why 57
Each signal is scored as a percentile of Detroit’s own history, so 50 is normal for this market rather than average for the country. The temperature is the weighted mean of the four.

Against the other markets
What this does not tell you
Tested against what happened next, this describes conditions now and does not predict them. It is published as a description, not a forecast.
The score is a percentile of this market against itself, so it says nothing about size: a hot small metro and a warm large one are not comparable in dollars. Building permits are residential, which is the only development series published monthly for every metro and is not a measure of commercial construction.
