Thanks to the hard working of the team. The proposal announced in https://twitter.com/feiprotocol/status/1380730707903795200?s=20 produces new chances of arbitrage.
the FEI price increased just because new arbitragers. finally they will take the eth of PCV. Both 0.9 and 1 are stupid choices. No change should make in this proposal.new proposals should be provide, and proposal: reweight PEG price = min(secondary market price + 0.02U, 1U) always maybe a good choice.
