For comparison, Aitchison variance drops 55% and total variation drops 99.7% across the same ladder. Shannon entropy barely moves.

In the tested energy datasets, entropy changed very little across the decimation ladders we ran. The geometric mean — a central CoDa operation — appears to act as an entropy-preserving temporal filter on these domains.

This means the geometric mean — the fundamental operation of CoDa — appears to be an entropy-preserving temporal filter. Temporal resolution becomes a free parameter. Information content is stable.
