that does not mean that blocks are grabbing all transactions 9sat up
it means SOME mining pools are selectively (pot luck lottery style) adding a couple random transactions outside the "highest fee first" jsut to seem reasonable.. the 9sat/b does not mean your 16sat/b has priority over say the 20sat/b ones
you just have to be patient

yes its annoying, yes bitcoin is made using code. yes code can codify rules of acceptance to be more fair, yes transactions can be analysed into a formulae where coin-age and "first seen" can produce a priority order... but many people that want bitcoin to be annoying to promote offchain systems as solutions to the annoyances, dont want the annoyances fixed
