Gauntlet recommendation for WETH Uopt on Ethereum v3

It seems during the 2023.8.17 volatility, WETH utilization did not increase. Is that because the price drop is not big enough, or that borrowers started paying back their debt?

Is there any evidence of the speed of debt repayment based on past episodes of volatility, eg: June 10-13 2022, etc?

It also seems this proposal somewhat offset the simultaneous proposal to decrease WETH slope 1 to 3.3%, which is meant to increase utilization. For the simulation above post, does it matter whether slope 1 is 3.3% or 3.8%?
