Iron ore blob size doesn't match with Java Edition

I'm not sure if MCPE-144078 is still an appropriate place for ore generation parity issues, since it has not been updated for two years, and it doesn't mention ore blob size. So I created a new issue about parity on iron ore blob size in the current versions.

Bug:

A normal iron ore blob is in size 9 (at most 13‌ iron ores) in JE, but in size 10 (at most 16‌ ores) in BE.

It can be checked in "assets/behavior_packs/vanilla_1.18.0/features/iron_ore_feature.json" file.

History:

This issue was introduced in 1.18.0.20, released on October 6, 2021. At that time, the newest version of Java Edition is 21w39a. In 21w39a (and current version), iron ore has a patch of blobs in size 9 that attempts to generate 10 times per chunk, and diamond ore has a patch of blobs in size 4 that attempts to generate 7 times per chunk.

In 1.18.0.20, many ore generations were tweaked to match Java Edition. However, for iron ore and diamond ore, there were two changes: The size of normal iron ore blob was changed to 10, and the size of normal diamond ore blob was changed to 7.

As a result, in 1.18.0.20, iron ore has a patch of blobs in size 10 that attempts to generate 10 times per chunk, and diamond ore has a patch of blobs in size 7 that attempts to generate 7 times per chunk.

I'm not sure if this was intentional. However, for diamond ore blob, its size was changed to 4 in Hotfix 1.18.1 and Beta 1.18.10.22. So that it matches Java Edition now.

However, normal iron ore blob size is still 10 in current versions, which doesn't match Java Edition.

An iron ore blob has 16 ores, which is too big. In JE, it is at most 13.

To compare with java edition:
Normal copper ore blob is in size 10 in both JE and BE. Here's a screenshot in JE shows that a 16 ore copper blob, which is generate with /place feature ore_copper_small command

Hi, I was unable to reproduce your findings from the iron_ore_feature.json file. For me, it displays the "count" as 9, like it should. Check the attached screenshot:

It is not consistent as described in the Description.
As mentioned in the Description, the file is at assets/behavior_packs/vanilla_1.18.0/features/iron_ore_feature.json. @KR_ showed another file at a wrong path.
