I'm not sure that's true. I find that those without an engineering
background find it counterintuitive and need a lot of time to get used
to it. At least that has been my experience teaching people to use
their 430's, 530's, etc.

What was the average age of the person you were teaching?

About average for the pilot-owner. That is to say, maybe 45.

Younger people always learn faster.

The interesting thing is that the ones who did have significant
relevant experience (I'm thinking a couple of engineers here) got it
instantly. The others needed a lot of work.
