Oops, you're right! I missed that bait and switch, where one formula was used for introduction, a different formula to demonstrate examples, and then switched back to the first for the conclusion.

The actual formula they implemented is ( rshares + s ) * ( rshares + s ) - s * s / ( rshares + 4 * s )

It's a bit more complex than explained in the deep-dive, and I don't feel qualified to explain it properly.

Thanks Joseph, that's helpful!

I had a check on github and it looks like "s" may be 2,000,000,000,000 rshares. Working through the formula on that basis gives a curve that:

Starts at 50% of linear (rather than 0% - this is a welcome change!)
But takes quite a long time to move towards approximating linear.

So a HF20 $0.10 upvote would:

initially add $0.05 to a post / comment under HF21.
be worth $0.08 ("80% consensus") around $6 payout.
be worth $0.09 ("90% consensus") around $16 payout.

Although there is also some scaling to take into account (since the lower rewards on smaller value posts would be spread across all posts over time).
