Now that Kyuranger has broken the standard giving us a post-anniversary show with a nine-member starting roster since Hurricanger do you think you would still like a sentai show that starts with three only for 2022 or wish it ditched that repetoir starting this year?
If you know your broadcast history for sentai ever since Gaoranger post-anniversary teams started as a trio and later added new members as the show went on.
So far it was Hurricanger, Gekiranger, and Go-Busters that was part of this cycle.

Well, 9 is 3x3 so from a certain point of view they still got the trend going...

True to a certain extent, but I'm talking about that Suvulcan/ Liveman type of beginning where the first arc is only three people fighting the baddies.

It's logic like that that tries to continue the numbering sequence after Decade-Fourze.

I only follow that "numbering sequence" ironically because it's absolutely absurd and the straw-grasping is a riot.

Didn't even the most tenuous claims fizzle with Ghost though? Or has someone found a way to link the Eyecons to the number 8, like how the lockseeds and Shift Cars kind of resemble their numbers?

The fact that some people still followed it was rather annoying, though. I think it only became a joke around Drive.

Drive's Shift Cars resembled a 7, and Ghost's G on the Ghost Eyecon looked like an 8.

And Gasshats look like the number 9 when you squint at them.

Kyuuranger is somekind of reboot ?

Yes. It's scrapping all the characters, zords, and continuity of the series before it. Totally a reboot. Not like any other sentai/rangers in any way.
