I hate when on lvl9 I push str just to mine some Quartz by 1% and then see that it is Q60

Sounds fair to ask for

I inquired about the reality of the situation—how rock quality changes with depth and whether there is a correlation. This is what I found.

"Yes, the quality of a rock (its physical and mechanical properties) is directly related to its difficulty of extraction. In mining, there is a concept called "rock hardness" (according to Professor Protodyakonov's scale), which determines how difficult it is to break a rock. Here's how extraction difficulty relates to quality:
High Strength = Difficulty of Extraction: High-quality rocks (high strength, hardness, and density—e.g., granite, quartzite) are more difficult to drill and blast. They require greater energy and time investment, as well as specialized tools.
Low Strength = Ease of Extraction: Weak, fractured, or porous rocks (clays, loose sandstones) are easy to extract, but their quality as a building material or ore is usually lower.
Fracturing: If a rock is strong but highly fractured, it is easier to extract, but the quality of the final product (e.g., crushed stone) will be lower due to the high content of fines.

Thus, the higher the quality (harder and denser) of the rock, the more difficult it is to mine."

I also saw a thread somewhere where they suggested significantly increasing the quality of rocks at level 8-9 (and adding level 10), so there is demand for this.
