Did another test while replacing the queue on my router with a big FIFO.
Still got an A+ score:

However, note the max latency in download; quite a few outliers, jet I
still get a jitter score of only 22.6ms. Also, this time there's a
warning triangle on the "low latency gaming" row of the table, but the
score is still A+. Should it really be possible to get the highest score
while one of the rows has a warning in it?
