Example: The standard size is 10 contracts, the baseline IV for July is 100%, the strike volatility ratio for the ETH 2500 strike is 1.1, and the skew impact parameter is set to 0.005. If a trader comes to buy 20 ETH July 2500 calls, the AMM will increase IV to 102%, and the strike volatility ratio to 1.1 + 0.005 * 2 = 1.11. These values combine to give us the IV input for the trade: 1.11 * 102% = 113.22%.
