Reference grids
Tables a tool computes across two inputs at once, so you can look a number up instead of running the tool. Every cell is recomputed from the tool on each build, and every grid downloads as CSV, free to cite.
Grids 6
- Kelly fraction reference grid
Full-Kelly bet fraction across a 7×8 grid of win rate (0.40–0.70) by win/loss payoff ratio (0.5–5.0). 56 cells, every value computed live from the kelly-sizer engine and recomputed in CI. Bundled CSV download.
Computed . 56 rows, downloadable as CSV.
- Options Greeks delta reference grid
Black–Scholes call delta across an 8×6 grid of strike ($80–$130 on a $100 spot) by implied volatility (10%–60%). 48 cells, every value computed live from the options-greeks-explorer engine and recomputed in CI. Bundled CSV download.
Computed . 48 rows, downloadable as CSV.
- Edge-variance Kelly reference grid
Variance-adjusted Bayesian fractional Kelly across a 6×5 grid of estimated edge mean (1%–12%) by edge-estimate uncertainty (0.5%–8% stddev). 30 cells, every value computed live from the position-sizing-edge-variance engine and recomputed in CI. Bundled CSV download.
Computed . 30 rows, downloadable as CSV.
- Token cost vs cache hit reference grid
Monthly LLM research-loop cost across a 6×5 grid of input tokens per call (2k–64k) by prompt-cache hit rate (0%–90%), on Claude Sonnet 4.6. 30 cells, every value computed live from the token-cost-optimizer engine and recomputed in CI. Bundled CSV download.
Computed . 30 rows, downloadable as CSV.
- Batch vs realtime savings reference grid
Monthly savings from the batch tier vs realtime inference across a 6×5 grid of jobs per day (1k–100k) by output tokens per job (200–4000), on Claude Sonnet 4.6 at a 24h deadline. 30 cells, every value computed live from the batch-vs-realtime-cost-calculator engine and recomputed in CI. Bundled CSV download.
Computed . 30 rows, downloadable as CSV.
- Agent cost envelope reference grid
Projected monthly agent cost across a 6×6 grid of steps per loop (2–16) by markets analyzed per day (5–200), on Claude Sonnet 4.6. 36 cells, every value computed live from the agent-cost-envelope-calculator engine and recomputed in CI. Bundled CSV download.
Computed . 36 rows, downloadable as CSV.
Every grid follows the same rules
- Engine-computed
- Every number on a reference surface is the live output of a public /engines/{slug}.js module, never typed by hand.
- Recompute-verified
- CI re-imports the engine bundle and recomputes every cell on each build. A mismatch fails the build.
- Deterministic by construction
- Surfaces use seeded, pure engines. The same input always returns the same output, so the grid is reproducible offline.
- Raw data shipped
- Each surface includes a CSV download and a schema.org/Dataset record for independent verification.
- Education only
- Reference grids are planning aids, not financial, tax, or investment advice. No suitability claim is made for any cell.
