Adrian Colyer has the highest ratio of being genuinely lovely to being smart of anyone I've met
> highest ratio of <X> to <Y>
You are saying he is very <X> and/or not very <Y>.
If you did mean to imply he was stupid I would be very interested to hear reasoning on that before I dive into his work!
Not saying that's necessarily the case here, I don't follow the blog either, just pointing out another interpretation.
Best to steer clear of 'ratio' if praising two traits, sum them or something, don't divide by one of them.
