>>1784303Long running APEX streams always have higher viewers than other streams of the same length. The difference is because the game encourages viewers to join and leave the stream in regular intervals which increments the view count unlike just F5ing.
A viewer joins, watches for a few minutes until Aqua's team is wiped, swap to another stream for a few minutes while Aqua queues&plays through early game, and then rejoin the stream.
This is also how the Sans fights got so many views total on Marine and Kanata's runs.
