Looks reasonable to me (but I'm not an engineer) - in case you didn't recognise the author he is a design engineer for Cessna and the chief designer for their LSA. So I would trust his judgement. But saying all that aircraft props are still a black art even 100 years after the Wrights invented the modern aircraft propeller. Every maker seems to have his own methods of measuring, airfoils, platform, etc. all of which contribute to the (prop's) success or failure in the real world.
When I plugged in my numbers the results (dia & pitch) are the same as what Streba suggested.
