Haider and Theodore appear together in 1 published list, across 29 years of shared records. Theodore held the stronger position in more years in 1 of them, Haider in 0.

In none of those lists did their order change and stay changed.

Haider reached its own highest recorded position earlier in 1 of those lists, and Theodore in none. Each position is a place inside its own list, so this compares when they peaked and never how high.

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.
