I did some testing with ult at level 6, so 200 second cooldown:

5% normal CDR + =  seconds (= % total CDR)

45% normal CDR + =  seconds (= % total CDR)

45% normal CDR + =  seconds (= % total CDR)

So yeah it's multiplicative as you say, so I don't really what you want me to do since you've already stated it. I slightly modified the description though:
