A Broadcast Audit measures how long each sponsor's logo was on screen in one race broadcast, where it appeared and how clearly. It then estimates what comparable advertising exposure might cost at stated audience sizes. These are the rules of Methodology v4.4.
Sampling and credited time
Computer-vision models look for the sponsor's logos in sampled frames across the whole recording: every 5th frame, about six frames a second for a 30 fps replay. Credited time is built from those sightings. When the sponsor is sighted again within 5 seconds, the gap counts as continuous; a longer gap ends the appearance. Logos smaller than 0.07% of the picture are not credited. Each moment counts once in the sponsor's total.
The Visibility Score and tiers
Each sighting gets a score from 0 to 100 from five factors: recognizability at its size, prominence, visibility, position and sharpness. Detection confidence is not part of the score. Tiers weight the valuation: Hero (Visibility Score 80 or more and at least 3% of the picture, weight 1.16), Standard (50 or more and at least 0.18% of the picture, weight 1.0) and Incidental (any other credited appearance, or one too blurred to read, weight 0.5).
Estimated media value
Estimated media value = (assumed viewers ÷ 1,000) × tier-weighted seconds × $0.50. The $0.50 is a PitSponsor planning assumption, not a published or negotiated market rate. Every report shows the value at five audience sizes from 25,000 to 200,000 viewers; 50,000 is an assumed planning audience, not measured viewership. Estimated media value is advertising exposure equivalency, not sales, conversion, brand lift or return on the sponsorship.
The sample check
For each placement, a PitSponsor reviewer checks 60 random credited moments against the recording. It is PitSponsor's own review, not an independent audit, and it does not establish that every appearance was found.
