How to read this page

Start with one-lot, A-tail and B-head. The table below defaults to the most likely pattern.
The three cards are more likely allotment patterns, not a ranking contest. Clicking another card only compares how the numbers change; it does not replace the main reference.
An extra-watch note names one pattern to compare first. Click it to see how the numbers change. It is not a new main reference and not trading advice.

More likely allotment patterns

“Most likely” is the default method for the current numbers. The other cards are next-likely patterns for comparison. Clicking them does not replace the main reference.

Win-rate forecasts are informational research output. Likelihood is the published scenario view. Extra-watch notes use forward-only historical samples, do not change the main-reference numbers, are not official allotment certainty, and are not subscription advice.
