Am I wrong to automatically give my opponent the 10 points for a painted army because I don’t think one’s painting ability is a gauge of their ability to command?

I always give my opponent 10 points when starting and logging the match even if they’re not painted. I know according to official GW rules this shouldn’t be the case but, like the title says, I don’t think it should determine who wins. I also think it can create create friction if even ONE model doesnt have 3 colors and basing.

If I should stop I will but I wanted to get other thoughts before continuing or stopping.

Cheers.
