Yes thats what I meant, extreme cross chaining is not recommended, whatever the sprocket/chainring sizes.

You really don’t have a clue what you are talking about. I would normally ask someone to explain a nonsense statement like that, but you would just come back with more ‘word salad’.
And btw, ‘efficiency’ has absolutely nothing to do with how ‘easy’ something feels. You are also confusing drive train efficiency with aerobic efficiency as though there is no difference.

This!
I rarely use 11t, I rarely use 28t at the other end also, but that's not an argument for having 12-23 cassettes!

There's a huge range of cassettes and chainsets out there. It's rarely that hard to find one to match your needs.
And remember, you can reduce the number of speeds if you wish, to get what you want. More not neccessarily better!

Really how much energy over an hour are you losing compared to a 13 teeth cog and why?

Good luck getting an answer - let alone a rational one. I think he's got me on 'ignore' as he can't answer the questions I ask him.

It's always baffled me why cassettes are all fixed... surely it'd make more sense (maybe not financial) to have (in my case) 7 separate sprockets and 7 spacers and a lock ring... that way i could tailor all the steps and radios to what i want (or think i want).

As I mentioned earlier in the thread they didn't used to be. And as I have said here before, that's how I ended up racing for over a season with two 18t sprockets on the back.
Anyone can make a mistake

It's so that the shifting gates line up with each other (i.e. the ramps and truncated teeth).
There are about 3 versions of each size sprocket, and if you use the wrong one, you're back at old-style clunky shifting.
You'd also lose out on the weight saving gimmicks, where 2 or 3 steel rings are mounted on an aluminium spider, so your free choice cassette would be heavier.

Sprockets used to be stamped with a figure '0' on the side and you needed to line those up.

The more you understand the physics, the easier you can make you life, and the more you should enjoy it. If you improve the efficiency, ( for a given effort ) you’ll go faster, or you can go as quick as you currently do, with less effort.

Quite a bit, unless you’re spinning it at the speed and power you need to be to make it efficient. That is subjective, but ( for arguments sake ) let’s say 90 rpm, with a minimum 150 Watts. That’s very difficult to do, with an 11 tooth sprocket, and most commercial chain sets, with an average rider. It’s as much about the rate at which you’ll deplete carbs, if you’re out of the ‘efficient band’ as energy wastage.

Awesome word-salad. Seriously, do you post from the twighlight zone, or something? This is absolute gold-standard nonsense and it reads as though you are completely clueless. Keep it up though, it's hilarious - as long as people don't actually take it seriously.
