RaceMetrics' System Builder now reads sectional timing data as back-testable filters. Users can construct systems based on finishing speed, run-out speed, and sectional upgrades — the same way they build filters from any other variable.
Coverage and the finishing-speed staircase
Every sectional system begins with one rule: only consider runners whose last race has sectional coverage. A tick-box in the desktop builder applies this filter instantly.
Breaking the cohort by last-time-out finishing-speed rank reveals a staircase pattern. The fastest finisher last time wins nearly 18 per cent of the time; the second-fastest, 15.5 per cent. Strike rates decline rank by rank. Users can convert any rank into a system rule with one click.
Two use cases
Demand a top-three finishing-speed rank. Adding this single rule to the coverage filter doubles the strike rate against the slowest finishers, producing wins at close to 16 per cent.
Hard-luck runners. The sectional model identifies horses that should have won last time, but for a single poor section. These runners win nearly one in five on their next start and have shown profit at Betfair starting price after commission.
Morning qualifiers
Once saved, a sectional system reads the day's declarations each morning. Qualifying runners are emailed to users and badged on the racecards before the off. This allows users to apply sectional filters as live racing information, not just historical analysis.
Requirements
Sectional filters require the Sectionals add-on alongside Proform Premium.
