Rank is only based on seniority but it doesn't mean that high rank members are more knowledgeable than the low rank.
Maybe some are more knowledgeable but not all of the high rank, based on how I evaluate myself, I still see that there are low rank that are smarter than me.
i agree with you. the rank doesn't necessarily have anything to do with knowledge. but without the gradation according to rank, which also has to do with the time you have already spent here, you couldn't build a fair system. but of course every system has advantages and disadvantages
