Hello, I fixed some grammatical errors here:

    1. "best practices for PRs" could be "best practices in PRs" for consistency.
       
    2. In the sentence "This saves time by reducing the number of rebases due to conflicts.", "reducing the number of rebases" could be clarified to "reducing the need for rebases".
       
    3. In the sentence "Similarly, too many review cycles is a burden for both PR authors and reviewers, and results in “review fatigue” where reviews become less careful and thorough, increasing the likelihood of bugs.", "is" should be "are" to match the plural subject "cycles".
       
    4. In the sentence "This is organized by current state of PR, so it can be easily be referenced frequently to help internalize the guidelines.", "be" is repeated, and it could be corrected to "This is organized by the current state of PR, so it can be easily referenced frequently to help internalize the guidelines".
