Plinio Watch

Well, I have a certain notion that most of those who report bugs here, especially betas, like me are more experienced players, and I also understand that an increase in the difficulty of finding certain resources is something that we would like, but we also have to think about those who play more casually and for less time than us. I spent almost five hours mining as I always did, looking in caves and making tunnels, to find just five diamonds. This is clearly something that would greatly detract from the experience of those who have less time to spend during a day and they could take up to a week if they did not know how to search correctly.
According to a quick count that I made, based on the general quantity and using the prints I brought showing the difference in the generation of diamond ores, I was able to make a numerical comparison in theory. The number of diamond ores in an area of ​​50 x 50 varies from 35-45 for version 1.16.221 and from 10-15 for beta version 1.17.0.54.
I believe it is clear that if it was a deliberate reduction or a bug that was maintained it would be very harmful for players with less time and experience, not to mention that it is a very big difference for an area of ​​3 chunks x 3 chunks
Note: The comparison of the number of ores was made based on my experience with the quantity in the generated sets, that is, in general the large sets have from 5 to 8 ores, and in the beta, if I am not visible the probability of having another just below is low.
Note²: A margin of error has been added to ensure that the numbers are not outside the actual values.
As a guarantee, if those who read it still have doubts, please run the experiment and perform the counting.

Here's another test I did. For him, I followed the same protocol as the first test (using the / fill command to remove blocks that were not diamond ore) but this time I ran the test in two situations: 1) Using the latest official version of Minecraft Bedrock Edition, 1.16.221; 2) Using the last beta version released until the date of this comment, at 1.17.0.54, without activating the Caves and Cliffs button.
Methodology: I separated a random seed for the test and assigned a random region for the experiment. After that, I designated a 50 X 50 area to remove unwanted stone blocks and ores, keeping only diamond ores. To ensure this, the / fill and replace command was used. Finally, the bubbles of diamond ores were marked with redstone blocks, 1 for each set.
Results: It is clearly noticeable a considerable reduction in the presence of diamond ores, not only in numbers but also in the quantity grouped (unfortunately I forgot to take the prints showing the quantity present in each cluster, but if they repeat the process they will be able to easily perceive).
This was the methodology I used to fortify my argument that the generation of diamond ores was, in some way, hindered. For added security, I ask that, if possible, those who see this post, perform a similar test on other maps and bring more information to reinforce or refute the post.
The seed used for the test was: 1356942840
The coordinates used were: X 2702, Y 91, Z -123 to X 2652, Y 91, Z -73.

The images referring to this test have been attached to this post.

I believe it shouldn't affect, because as the Caves and Cliffs update will be divided into two parts, the first being just the blocks and mobs and the second being the update of the world and structures, the generation of ores should be normal as long as I don't activate the function of generating the new caves and mountains.
So I think it is a bug, as I do not believe that the generation would be so affected this way until the end of the year when the second part of the update comes out.

Yes, i am aware of these generation changes of the ores but should it also affect the generation when the button to activate or deactivate the new caves is also deactivated?

same here. I included a video to show.

Here too, but the craft for me is working, just not appear in the guide. Same for torches.

Oh, it's right! I have this test map a long time and didn't see the settings, thanks for warning! it's possible exclude the post? First time here.
