Record Rating in detail why the number is what it is
Limited Optics #1918 of 6,292 worldwide
Stage skill
79.5
hit factor as a percent of the pace that wins an average Limited Optics field, fitted from 100 stage results since Oct 10, 2024
Blow-up deduction
−0.0
0 zeroed stages, a rate of 0.0% after a light pull toward the division; a zeroed stage scores nothing, so the skill is cut by that share
Record Rating
79.5 ±3.9
interval 72.2 to 87.5 at two deviations; personal stage noise 17.4% per stage; US level known to ±0.6%
Ordered by
75.7
rating less one deviation; a short record must be exceptional to outrank a long one

Class rank

USPSA class order (U), ties by avg %
Every match in the fit, oldest first. Percent is the raw percent of the division winner. Versus stages is how far the day's hit factors ran above or below the measured difficulty of the stages, averaged; best and worst are the single stages. Flagged stages fell more than two personal deviations from expectation and were given reduced weight. Skill is the fitted skill at that match on the random-walk path; the last value, before the blow-up deduction, is the stage skill above.
