I think the next steps here are to implement the top-up of the DPI LM rewards according to @george’s spec above. IIP-28 was voted in by the community, and until another IIP is voted in to override that decision, it seems the Coop should honor that decision.
If we want to update the LM parameters for day 60 - day 90 of DPI/MVI Liquidity Mining, I suggest someone draft an IIP!
