Comparative & Time
What the race actually said — a boat's sailed pace against its rating expectation, record by record.
Comparative & Time (registry short label: Performance) is the FleetEdge dimension family that reads the race record itself: how a boat's elapsed pace compared with its rating expectation, how many comparison records stand behind that reading, its Race PPI, and its best finish on record. Every reading here needs a race result — these are the race-dependent dimensions that open the Fleet View ribbon and the Boat View.
What Comparative & Time measures.
Four readings, each one a race-record fact. The comparative reading is the spine of the family: the boat's sailed pace set against what its certificate rating expected, in seconds per nautical mile (sec/nm). The rest say how much evidence stands behind it, how the Performance Potential Index scores the race record, and how high the boat has finished.
| Dimension | Unit | Reading |
|---|---|---|
| Race Performance vs Rating Expectation | sec/nm | The boat's sailed pace against its rating expectation, race by race — negative is faster than expected, so lower is better |
| Comparison Records | count | How many race comparison records stand behind the reading — higher is better |
| Race PPI | 0-100 | The Performance Potential Index scored on the boat's race record — the full score, crew execution included; higher is better |
| Best Finish Rank | # | The boat's best finishing position on record — a finishing order, so lower is better |
Reading the polarity. A comparative reading is seconds per nautical mile against the rating expectation: negative means the boat sailed faster than its rating expected, so the most negative reading is the strongest and a ranked board lists it first. Race PPI and Comparison Records read the other way — higher is better. Best Finish Rank reads like a finishing order — lower is better. The labels and units are the App's own, the same family you see first on the Fleet View ribbon and as the Comp & Time story in the Boat View.
Where the family renders.
In the Fleet View, Comparative & Time is the first family on the dimension ribbon: the fleet in view ranked on its comparative reading, with the rating expectation as the zero line on the career board (an event-filtered board re-centers on its cohort). In the Boat View, it is the Comp & Time story — the boat's race record read against expectation, one record at a time, with the crew and condition families explaining what the comparative reading alone cannot.
The expectation a comparative reading is set against is the boat's certificate rating. FleetEdge reads that expectation; it never revises it.
What a comparative reading can and cannot say. It places a boat's sailed pace against its rating expectation on the races in coverage, at a stated record count. It cannot say why — design, crew, and conditions are read by their own families — and a single race is an anecdote until the record accumulates.
FleetEdge alters no rating and no score — ORC remains the rating and scoring authority.
