Plus with this you get reliable index shifting, easy access to parts and replacements. It’s so much easier to work with and on than a cobbled collection of vintage and outdated gear. Especially if you are using the system for touring or traveling.
This has never been rocket science. You get onto a long climb, you go to the granny when you run out of momentum in the middle ring. You work your way up the cogs as the grade increases, you don’t for a minute think that perhaps the gear you are in is also available somewhere in the middle ring. You stay in the granny and grind it out, when the grade eases and you get down near the small cog in the granny, you shift the rear up a bunch and then go to the middle ring. You don’t ponder the exact shift, I don’t have DI2 in my head.
