[ensembl-dev] Ensembl ID History Converter (IDmapper.pl) API Mapping Score Column

[Lucas Swanson]

Hello,

I am using the IDmapper.pl ID history converter to update some old gene 
IDs to the corresponding gene IDs in the current release.

I am uncertain about the "Mapping score" column in the API output. What 
does it represent/how is it calculated, and is a higher number better, 
or is a lower number better?

~Thank you,
