Somewhere right now a pizzeria owner is staring at a number, googling “is 8.3 good”, and quietly spiraling. This index exists to end that. School taught you 83% is a B-minus. Pizza is not school. On his current scale an 8.3 beats — of everything he has scored in the past year. You are not mid. Please call your mother.
One number, no context, delivered on a sidewalk to a man holding a paper plate. Nobody has ever known what it means. Not the owner, not the customer, not the guy who drove ninety minutes on the strength of it.
A 7.2 in 2016 and a 7.2 today are not the same pizza. His floor has climbed from — to — while the ceiling never moved. Your score is competing against a completely different field than it used to. Nobody adjusted for this. We did.
All — reviews, ranked, era-adjusted, and translated into the only thing that actually matters: where your score truly stands. Then we build you a graphic to post about it.
This is what an unexplained number does to a person. Every one of these is preventable. A score is not a verdict — it is a position in a field of —, and the field has been getting easier for a decade.
The Portnoy Score Index — doing the math nobody asked for, on behalf of pizza.
Same percentile, different year. Grey ticks on the rail are every score he gave in the last 12 months. The outlined year is the base year for the one-line verdict.
Calibration set. All scores except protest scores below 1.0 and the 14 retro-logged reviews dated 2013–2015. Everything is computed from this set; the excluded records still appear in the ledger with a badge.
Percentile now. Rank of a score within the trailing 365 days of calibration scores (mid-rank on ties).
Year equivalents. Quantile mapping: take the score's percentile now, return the score at that same percentile in the target year, interpolated. It corrects for the average and the spread at once — which matters, because his top decile has held at 8.1 for years while his floor rose from 3.9 to 6.8.
Search every review by score, place, or venue name — or use your location.
Pins show his score. Red 8.5 and up · black 8.0–8.4 · white 7.5–7.9 · grey below 7.5. Distances are straight-line. Tap a pin for the review.
