The Spin & Go tournaments are well advertised and attract a lot of recreational players.
If we exclude the jackpot of 3600 buy-ins which drops down once per 100,000,000 tournaments, the rake of 5% or 6.2% at higher stakes makes these tournaments attractive for professional poker players.
However, if you wouldn't play an infinite number of Spin & Go tournaments, your rake will be 5% only in theory. In reality, this percentage will be higher if you're unlucky, or lower if you are lucky. You can spend a lot of time, but actual winnings will never match with the theoretical mathematical expectation.
