2 Cards in two Wallets

Hello,
My Rig Specs: RTX3080 + RTX3090 on Hive Os Ver 0.6-199@210218

I want to mine each card into a sep. wallet.
I set up 2 dif. Wallets
I create a Flight Sheet with a second Card
First Miner phoenix miner, second nanominer. (Only with this two miners the GPU Device Settings work)
Now I have a general Hashrate from 195 MHs
With only one miner (phoenix) i get 223 Mhs
Is my workflow to seperate the coinflow to two wallets corekt ?

Thanks for reply (sorry for bad English)

Anybody a Idea or Link ? In this Forum i cant find any help
