My opinions about 1x cassette ‘gearing’ – how can it be improved imo

I really love 1x system. Simple af, also no 'front derailleur' means much less fuss when shifting
(Never used electric ones tho)

But, (old-ish) 'gravel' cassettes(11-42, 10-44, etc) has a bit too narrow range for my taste(<450%)

And super wide range MTB cassettes(10-52, 9-45, etc) has too much gaps between gears.

Evenly spaced gears for MTB cassettes makes sense for Mountain riding, because they encounter lots of uphill and downhill.

But for gravel riding, I think more 'cruising gears' would be beneficial for some riders, which includes lots of flatty on road riding.

The pictures shown is gearing of my 'suggested' 12 speed 9-45t,
versus Shimano 12 speed 9-45t,
And Sram 13 speed 10-46t XPLR.

My suggested gearing has very close gaps between 13~20t range which is 'cruising gears' for mixed roads/flatty terrain, added with 2 very fast gears, plus some low and really low climbing gears.
It will give plenty of cruising gears when flat, occational high gear at long decent, and plenty range for climbing when needed.

Comparing to 'MTB' Shimano 9-45t, it has same total range. But at the cruising gears, the gap is still kinda large, when pedaling constant really matters.
And, Its much worse with traditional 10-51/52t mtb cassettes.

Comparing to 13 speed XPLR, added one gear and the slightly smaller range really helps the gap of gears being smaller.
But… added gears all goes into very high gears. Like, using 13t or higher would be very rare (maybe under 5% of total riding time) for my riding style…. so 4 gears are kind of 'wasted'

And ofc, this concept would also work with another kind of gear configurations

So… whats your opinion for a gearing like this?

Ps. My cruising speed is relatively slow at 20-30kph, so 34t chainring for 9t~cassette, and 36t chainring for 10t~cassette roughly matches the total range I need. If you're a faster rider you'd better use a bigger chainring btw.
