They don't have to match exactly, but I couldn't tell you how far is too far.
I've heard of people running 4.10/4.11, so your 4.09/4.10 should be okay. I'd call a couple gear vendors and get their expert opinion.

From what I have read the gear sets need to be within 1%

I've heard that a difference of .04 is ok. Like RangerX said, check with a gear vendor to get an expert opinion. We don't want to be the cause of your gears messing up
