We’ve sent bribes for previous periods on wstETH pool as well, and intend to continue for now.
The 20% of earnings focusing on DEX token purchase sounds significant, and that would be the q of capital efficiency. From our initial research, 1) purchase would be 1.5x more expensive to get the same amount of incentives than just sending LDOs to gauge; 2) bribes on HiddenHand seem to be ~3x more efficient compared to direct incentives.
I totally understand that those numbers are to change with the market (bribes getting lower efficiency with time & BAL price moving), but for now that wasn’t something we were planning to consider short-term.
