Who is 'we'? Do you have a mouse in your pocket?
I don't see much gray about the code in question 'shall be the same length'
Where is the gray in that?
Well yes in most case you could by cutting all the conductors the same length and leaving 'messy' slack at each end. But that was not what I said.
What I said was you should be making every effort to make them the same length without thinking, or concerning yourself with how it look
You are not the only one that has run large parallel groups of conductors.
My only point here is your should be placing equal length head of 'pretty'
