Reading off that 2e12 contingent linear rewards curve...

Under HF20 a post receiving $1 in upvotes would give the author $0.75.

Under HF21:

• The reward pool will be 10% lower to fund the SPS.
• The CLRC will reduce the payout by a further 40% compared to linear.
• The payout to the author will then be 50% (rather than 75%).
  I make this: $1 * 90% * (1 - 40%) * 50% = 0.27 under HF21

So broadly: $0.75 under HF20 vs $0.27 under HF21, a reduction of about two-thirds for smaller payouts.

Have I understood that correctly?
