What's up with MIUI version numbering? - Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D

I can see from the firmware listings below that the Redmi K20/Mi9T Pro is on a cluster-fudge of different version numbers:
https://mirom.ezbox.idv.tw/en/phone/raphael/
Global: V11.0.2.0
China: V11.0.5.0
Russia: V11.0.1.0
India: V11.0.3.0
EEA: V11.0.4.0
Are these numbers incremental?
The release schedule shows the latest updates hit the channels for Global and EEA on 10th January. Their update versions are 11.0.2.0 and 11.0.4.0 respectively. On the above website the changelogs are similar for both. I'd assume that this could be the same update just numbered differently given it was released the same day on both channels; though it could also imply the Global channel is two updates behind. Which is it?
I can understand Chinese updates being newer but are all other regions on a wild mish-mash of versions
Edit: My best guess from what I've seen now is that the same update is released for India, China, EEA and Global with various commits added or removed - and in that region order going by dates. The current Russia update is clearly still on the initial MIUI11 update; not the second on the other four channels

It used to be much more f'd up than that before. They used to number latest version with lower number. For example their 9.xx.xx versions were latest and 10.xx.xx versions were older.
At least now they use the same base numbers and are incremental. lol

This isn't strictly true.
Stable ROMs are numbered as per standard, ie. Major version.minor version.build
So currently we're on major version 11, this is the first version of 11, so the minor version is still 0. The regional versions are on different build numbers though. China is on the highest build, 5. Therefore the latest stable Chinese release is 11.0.5.
Beta versions use a different system. The beta version numbers are based on the date of release, rather than actual release versions and are year.month.day. Last year, they used the final digit for the year. E.g. A beta version released on the 15th Dec 2019 would have build number of 9.12.15.
Since the new year, to avoid having the version number starting with zero, they have moved to using the last 2 digits for the year. So now e.g. A beta version released on 15th Jan 2020 would have a build number of 20.1.15
All this only explains for observation of differences between stable and beta releases. As for the OP question of differences between the stable release versions of the different regions, unfortunately I've yet to come across any insight in to the differences of versions numbers across the regions.

Yea, I said it used to be. And the beta versioning system still sounds all messed up. People will have a hard time to understand why they are doing this.

It basically depends upon the laziness of developers of those regions.
