Constant MAX_EVENTS_PER_MARKER 

pub const MAX_EVENTS_PER_MARKER: usize = 16;

The most events one marker column gives; past it, the column’s rises are counted in a note instead. A marker marks one event of the flight (Quantum p38, Proton p46): as of 2026-10-12, no marker column among the 43 Eggtimer files in the project’s sample logs rises more than once. The cap keeps a file whose marker flips on every row from filling the record with events.
