Appendix A
Appendix B
Each Trial's 0–100 display score is pinned by two anchors, and neither is a guess. The 100-point anchor is a measured perfect run: flown, recorded, and extracted from flight data, plus a small pad for competition realities — PRECISION's includes the measured, unavoidable time above the altitude cap in the attack pops; ACCURACY's includes a 10-rounds-per-kill gun standard. The zero-point anchor is a ruled span below it. 100 sits at our assessed physical limit — a score above it is treated as exceptional and draws an automatic review of the run's scoring.
The spans were set through a purpose-built scoring simulation: the canonical scoring formulas, seeded with the measured baseline flights, generating more than 30,000 simulated runs per candidate clamp value and re-tested with every field assumption pushed both tighter and sloppier than expected, so the selected values had to hold everywhere, not under one guess. Those values converge the three Trials' score spread at sigma 0.65 / 0.67 / 0.70 (SPEED / PRECISION / ACCURACY) — near-identical, so each Trial carries equal weight in the Total Trials Score — and the imbalance they corrected was visible in the measured spread of the OTS-2 qualification submissions. Clamp values are re-tuned only between competition windows; every change is versioned, published, and recorded in the Release History.

Every published change to the competition framework, newest first
The PRECISION scoring pane publishes the Precision Display Score normalization — PDS = 100 × (TZERO − Tprec) / (TZERO − T100), with T100 = 340.5 s and TZERO = 1,840.5 s. PRECISION had been the only Trial publishing a raw score with no 0–100 conversion, leaving no published path from a Precision Raw Time to the Total Trials Score. Every term in the raw-time formula now carries its constant, and the MRP/URP wording is corrected from “% × 100” to the ratio the specification defines — a text defect only, no scored value changes.
The normalized-score anchors for PRECISION and ACCURACY are re-anchored to measured perfect-run flight data plus a small pad, sized so all three Trials contribute comparable score spread to the Total Trials Score (PRECISION T100 340.5 s / TZERO 1,840.5 s; ACCURACY ABEST 85.19 s / AZERO 335.19 s; SPEED unchanged; penalty values untouched). Appendix A now publishes the aggregation method as flown: Total Trials Score = the sum of the three normalized display scores — the placement-points table is retired.
The overshoot defeat-precedence rule is corrected to one-sided suppression: only a defeat that would credit within 1.0 s after a credited overshoot is suppressed — the overshoot maneuver itself never also pays a defeat. A defeat credited before the overshoot stands, because defeating the gun employment and forcing the flush that follows are two separate defensive achievements. No scorer change — the scorer has always applied the one-sided rule; the earlier “±1.0 s” spec/SPINS wording was the error.
A Forced Overshoot is now credited only to a competitor reversing out of a defensive state — the crediting competitor must have been on Defense within 10 s before the earlier of the two role-reversal crossings; an overshoot cannot be forced from Neutral. The scorer's overshoot detector was rebuilt to anchor on the two published angle-off-nose crossings (scorer v13.31), with hold, cooldown, and defeat-precedence unchanged.
The DOGFIGHT scoring pane now publishes the complete Forced-Overshoot detection — the two angle-off-nose crossings that define a role reversal, the timing window between them, the ≥ 0.50 s hold, cooldown, and defeat-precedence — matching the full-detail treatment of every other term (it was award-level only before). In the same pass the pairing window between the two crossings was widened (0.60 s → 1.5 s, scoring spec BFM v1.8) so a slower, wider flush still scores; award (+15 s), hold, and cooldown unchanged.
Pursuit now requires 8 continuous seconds of chase geometry before it credits or activates scoring, up from 5. At 5 seconds the gate was firing on ordinary post-merge extensions — a fought set that separated for ~15–20 seconds could hand the chaser a set-dominating Pursuit Time that had nothing to do with running the clock. Eight seconds filters normal extensions and reattacks while still punishing a genuine one-sided run, which lasts far longer. Chase cones, the 5.0 kft range gate, and the 3.0 s-per-second rate are unchanged.
Scoring now activates the instant a competitor holds pursuit geometry for 5 continuous seconds — Fight’s On triggers and Pursuit Time accrues right then, instead of waiting for the 20-second Merge Window. A runner no longer gets an unpenalized head start; the Merge Window now governs only mutual refusal (0-0 and stands).
The DOGFIGHT scoring pane now publishes the complete Unified Impact Score specification the scorer runs — engagement states, all term definitions, activation and Merge Window logic, Gun Solution and Weapons Defeated detection thresholds, kill handling, tie-breakers, and a constants reference — replacing the earlier simplified subset. Broadcast nicknames removed from the scoring terms; Control Zone floor stated as 800 ft.
Running from the fight is now scored against the runner: a pursuing competitor accrues Pursuit Time while chasing a fleeing opponent, and one-sided running activates scoring at the Merge Window rather than banking a 0-0. Makes refusing to fight strictly losing at any cumulative lead.
Discord replaces SRS as the required voice platform for OTS participation. Live event voice communications run in the SFL Discord event voice channel; the BLACK 01 / YELLOW 02 / BLUE 03 frequency nets are retired.
UIS scoring and the match clock start at Scoring Activation — first closure inside 1.0 NM after "Fight's On." A set with no activation inside the 20-second Merge Window is terminated by CLASSIC and recorded 0-0. Defensive spoil time now credits at half rate (0.5 × TDENY) — offensive pressure out-pays denial.
Dogfight tie resolution restored to the four-step cascade ending in a sudden-death re-fly. Charter § 3.3.4 corrected: set-1 altitude assignment is fixed by seeding — higher seed takes the high fighter.
All four event SPINS republished in the interactive HTML format — the baseline for the current SPEED, PRECISION, and ACCURACY briefs.
Charter and Appendices migrated from PDF to interactive HTML. Competition-framework figures updated; § 6.2.8 Returning Competitors added to the Online Tournament Series qualification process.
