It goes up an exponential hill very early on until just before the seventies, where it becomes linear. This is so apparent on a graph. They picked quite a big growth constant, so I guess that's why they flattened it using a linear scale instead My initial thought was that they didn't plan on levels beyond 69, therefore they didn't foresee the absolutely huge increases that will follow in the level 80s. I wonder.

Logarithmic??! Lol I don't think so!

Looks the same, just starting point is different. Very different.

It's late at night, so I mistyped for one rare instance. Go figure.
