How to use --dual-algo-mode a12:r10:lr12 of the latest version 2.59?

[wfndh]

What do the parameters of this new version of dual mining ETH+alph mean? --dual-algo-mode a12:r10:lr12 What does this sentence mean? I have always wondered how to use it. I have 8 3060TI graphics cards to mine ETH+alph. How to set it up? What does it mean by weight ratio? What I want to achieve is that the ETH hashrate reaches the maximum hashrate of 74 unlocked, and the remaining 26 hashrate is locked to mine ALPH. In this case --dual-algo-mode a12:r10:lr12 How do I use this command What is the setting to achieve what I said?
