TLDR: you cannot.

I am saying they are independent concepts. Basically, if you stay for one year it is not possible to learn the effects of longer projects (very valid point you mention). _But_, staying 10 years does not mean necessarily that you did learn from 2-3 years cycles. It will be _possible_. It could mean you are very good at deflecting, coasting, or playing golf with the right people, among many other possibilities.

Unrelated: today is on the news that Unilever's CEO will be resigning after 3 years, which also seems short to me.
