About the rule
The first row shows the full strip. Each later row shows the part kept by one choice. The previous rows stay visible, but cannot be chosen again. Each division is one third of the remaining length from its left end.
The study stops offering choices when the remaining length is less than one sixty-fourth of the original. This is an imposed display limit. It is not a property of a physical material.
Begin again clears these rows. Reloading does the same. This page does not save or send your choices.
