Showing Our Working

Four pages about our own claims: what we measured, what we deleted, what we never published, and what happens automatically if any of it drifts. Nobody else is named on any of them.

• The House Edge, Measured

  Two figures, each with the uncertainty that belongs to it, and the conditions they were measured under. This is what a number looks like when somebody actually computed it.

• The Number We Deleted

  We published a figure about our own subject for years. Then we built something that could check it, and it turned out to be wrong. This page is the deletion.

• Our Claims Can Break the Build

  The figures on this site are not stored as text. They are re-derived every time the software is compiled, and if a figure stops matching what the engine measures, the build fails and nothing ships.

• The Sentence We Never Published

  We wrote a line about our own subject that everyone in the room believed. We held it, measured it, and found it was backwards. It never reached a page — and this is the record of why not.
