Research

The record,
losses included.

Every call we published, graded against the price we took. Every question we tested, with what did not work. What the method did on past seasons, kept apart. And how to check that nothing was removed.

Did our calls win?

Our graded calls, week by week: coming once the published record file is served, at the first data refresh after it is built.

Every call, including the losses

Every call we published: coming once the published record file is served, at the first data refresh after it is built.

What we tested, including what did not work

Every registered question and its verdict: coming once the research record file is served, at the first data refresh after it is built.

Before the site existed: the backtest

Everything in this block is replayed history, not calls we published. It answers a different question from the record above, and no figure here is combined with one there.

The backtest over past seasons: coming once the backtest record file is served, at the first data refresh after it is built.

Why believe nothing was deleted

Append only
A call is written before its game kicks off and is never removed or edited; its result is added beside it.
Tamper check
Each ledger row can carry a fingerprint of the row before it, so editing any row breaks every row after (hash chain).
The ledger's tamper check: coming once the ledger carries its chain and the published record carries the chain's head.
Registered first
Each question is committed to the public repository when it is registered.
The dated commits beside each question: coming once the research record file is served, at the first data refresh after it is built.
The raw ledger
Every call as the file records it, row by row, on Receipts, and the file itself as CSV. Every decision about how the site works is in the decision log.
