Ernest and Isaac over time

Ernest and Isaac appear together in 2 published lists, across 45 years of shared records. Isaac held the stronger position in more years in 2 of them, Ernest in 0.

The order between them changed and held in one of those lists — a change in that published list, never a claim that one name displaced the other.

Each reached its own highest recorded position first in 1 of the lists they share.

Counted list by list. Two names in the same published list are measured on the same scale in the same year, so those comparisons are real — but positions from different lists are not, so nothing here is combined into an overall standing.
