Alistair and Jac over time
Alistair and Jac appear together in 1 published list, across 29 years of shared records. Jac held the stronger position in more years in 1 of them, Alistair 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.
Alistair reached its own highest recorded position earlier in 1 of those lists, and Jac 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.
