Record Rating in detail why the number is what it is
Production Optics #943 of 990 worldwide
Stage skill
45.2
hit factor as a percent of the pace that wins an average Production Optics field, fitted from 40 stage results since Oct 18, 2024
Blow-up deduction
−3.0
3 zeroed stages, a rate of 6.7% after a light pull toward the division; a zeroed stage scores nothing, so the skill is cut by that share
Record Rating
42.2 ±3.4
interval 36.0 to 49.4 at two deviations; personal stage noise 24.9% per stage; US level known to ±0.9%
Ordered by
38.9

Class rank

USPSA class order (D), 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.
