Documentation of plural rules

I have drafted a list of Mediawiki plural rules for all languages. I would be grateful if a translator could check that the rules for Tigrinya are correctly recorded in the list. If I have made a mistake please go ahead and correct it.

It could also be useful to any future new translators for Tigrinya to be able to read notes on using plural, especially Mediwiki plural, on your portal or a sub-page of the portal.
