the problem is when you're cut beyond a collection point, fly out of the way, and get put back on your route over the collection point. It's not the shortcut that increases your eta, it's flying out of your way and doglegging back. TMU doesn't catch as often as they should, but occasionally they do, or even better you get down the road and get sequence vectors when over the wind route you may not have, particularly if there's a GDP running.
Your years of flying the wind route doesn't translate to knowledge of the system and how it functions as a whole.
But, continue to be like the orange and blurple guys and ask for the next fix beyond the fix you have at every sector you check in, in the end it hurts you and your company.
