Fiona and Sigrun over time
Fiona and Sigrun appear together in 1 published list, across 25 years of shared records. Fiona held the stronger position in more years in 1 of them, Sigrun 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.
Sigrun reached its own highest recorded position earlier in 1 of those lists, and Fiona 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.
