I am the one that offered the last advice in this topic four months ago.
Even today, I have a “review this code you wrote, because despite your high comprehension, tokens that were printed are generated by a random sampling process that may not have been ideal, introducing errors”.
I am guessing that you are not simply taking a satisfaction survey, but have your own issues that are distinct from what has previously been answered.
You will get better forum answers if you tell us what on-topic concerns you are facing yourself.
