I'm assuming the first is based on these examples:
{cha' DISmo' jIH qan law' SoH qan puS} "I'm two years older than you."
{cha' 'ujmo' jIH woch law' SoH woch puS} "I'm two {'uj}es taller than you."
But wouldn't it be {cha'vatlh vatlhvI'mo'...}? When you're dealing with percentages, you're not saying "100% more", you're saying "200% as"... I think.
What about something like:
{vIghro'wIj tIQ 'IH law', vIghro'lIj motlh 'IH puS; cha'logh 'IH}?
I don't know what it means to be beautiful twice, either, but maybe it's twice as good as being beautiful once.
