As per CLDR this language (gv) has only one plural form
<pluralRule count="one">n mod 10 in 1..2 or n mod 20 is 0</pluralRule>
But, in MW, we have 4 plural forms
Form 0 = n mod 20 is 0
Form 1 = n mod 10 is 1
Form 2 = n mod 10 is 2
Form 4 = everything else
This is not at all compatible with CLDR.
Suggestions:
We can inspect how the plural forms are currently used and contact linguists and native speakers to verify. Depending on the results we can consider whether we can handle these with 1=foo exceptions or whether we need to push a change to CLDR.
