Fix: something meaningful

[fl124804gmailcom]

I optimized the test suite by reducing unnecessary repeated asynchronous calls and simplifying several expressions. In places where the same data was fetched multiple times, such as tokens or pools, the value is now retrieved once and reused. This makes the tests more efficient and easier to reason about, while keeping their behavior unchanged.

I replaced lambda expressions inside map with generator expressions in sum calls, which improves readability and follows common Python best practices. I also slightly reorganized variable names so they better reflect their purpose, for example using token, pools, epochs instead of short or less clear names.

Additionally, I added concise inline comments to explain the intent of each test and the meaning of non-obvious operations. The comments focus on why something is being tested rather than restating what the code already clearly shows. Overall, the structure and logic of the tests remain the same, but the code is now cleaner, more readable, and more efficient.
