Jeffrey and Kasper over time
Jeffrey and Kasper appear together in 2 published lists, across 34 years of shared records. Neither was ahead in more lists than the other.
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.
