Regardless, 8 spokes dealing with the torque is a non-issue. Spoke tension increases from pedaling force are very, very small.
I think from reading Jobst Brandt and others.
Btw, just checked. I was wrong on the stat. Typical thin-centered aluminum-shell hubs will transmit 13% of torque to the non-drive-side flange.
The 5% comes in reference to your second comment - spoke tension differences caused by pedaling torque, on the drive-side of a rear wheel with low-flange hub, will come in at about 5% increased tension in trailing spokes and 5% decreased tension in leading spokes.
