THE SATURDAY EXPERIMENT / READING GUIDE

Make sense
of the cards.

Start with the four. Keep the uncertainty in view.

How the race day works

The first read is the starting point.

The model rules stay fixed for the meeting. New evidence from earlier races can change the calls for races still to come.

BEFORE THE DAY’S RESULTS

The cold read

The opening assessment uses the horses’ form and the known race conditions. It has not yet seen how this meeting is unfolding. Treat the morning card as a starting point.

AFTER EACH EARLIER FINAL

Refresh the next races

Once an earlier race is final, the day layer reassesses the remaining races using that result. Emerging jockey, stable and barrier patterns can change the percentages, order or membership of the four.

Check again after each earlier result and before your race jumps. A new assessment can also leave the picks unchanged. Interim results do not count.

WHEN THAT RACE JUMPS

The call is frozen

That race’s last issued selections stay on the record. Its eventual result can inform later races, but it cannot rewrite its own prediction.

For Race 7:Morning read R1 final R2 final … R6 final R7 jumps and freezes.

Look for the issue time and the latest earlier result used on the card. If the preceding result is still pending, the card has not absorbed it yet.

The running total

Base and day-adjusted,
across the full record.

Across the same 79 scored races, the base four held 54 winners. The day-adjusted four held 57.

Base reference54 / 79 68%
After day updates57 / 79 72%

9 meetings · 26 September–31 October 2026 · R1 excluded. Final, scored races only. Both bars use the same 0–100% scale.

The day layer added 5 winners to the four and removed 2. Winning leans: 22 base and 22 adjusted, from the same 79 races. These exploratory results span model versions and do not establish a reliable general advantage. The comparison uses each race’s saved base and adjusted forecasts, rather than an unchanged morning card.

01 / Read the card

What you’re looking at.

Read each selection’s role
alongside its estimated chance.

2869

The box

Four horses, identified by their saddlecloth numbers. In this example: 2, 8, 6 and 9. Start with all four horses. Read their form, watch how the race might unfold and decide what deserves a closer look.

★THE LEAN

A preference, not a certainty

The lean is the model’s first-ranked selection. It has won 22 of the 79 scored races in this window. The other three matter.

◇THE UPSET

Fourth for a reason

The fourth-ranked horse occupies the upset slot. It remains part of the box, even when the model gives it a small chance of winning.

No. 8

The large number is the saddlecloth.
Use No. 8 to identify the horse. “Box rank 2 of 4” is the model’s preference and is shown underneath in smaller text.

11.7%

The model’s estimated win chance.
It is not a price or a promise. Calibration is still being tested.

A past result to explain the card. Not a current recommendation.

02 / Read the confidence

How clear is the picture?

Race confidence describes the model’s view of the whole field. It is separate from any one horse’s percentage.

Strong

A clearer view

The model sees more separation between the runners. It can still be wrong.

2 / 4winners in box · lean won 1 of 4
Fair

Some separation

There is a reasonable view, with meaningful uncertainty. Read the whole box.

8 / 10winners in box · lean won 4 of 10
Weak

An open race

The model has little conviction about the order. Treat the four as a shortlist to explore.

15 / 22winners in box · lean won 2 of 22

Dated example, 3–17 October 2026: 36 races. These are small samples, not promised success rates. Bars are ordinal labels, not calibrated probabilities.

What about Back / Small / Pass and the horse labels?

Earlier cards pair Strong, Fair and Weak with Back, Small and Pass. These are the original published tier names, not instructions to stake money. The day layer can lower the tier but cannot raise it under the current rule.

High, Medium, Low and Speculative describe individual selections. They are model labels, not independently calibrated guarantees. Read them alongside the horse’s model percentage.

03 / Put it together

A quick race-day routine.

  1. 01

    Choose the meeting and race.

    Check the date, conditions and issue time. Refresh after each earlier final result; check which earlier race the card has absorbed.

  2. 02

    Read the confidence, then the four.

    A Weak race deserves a different reading from a Strong one. Don’t turn a lean into a certainty.

  3. 03

    Compare the call with the result.

    Open the base comparison to see what the day’s evidence changed. Once the race jumps, its last issued picks stay beside the result.
