Wahoo Kickr Snap Zwift calibration?

So what’s the deal with calibrating my Kickr Snap. Wahoo told me you need to do 2 complete revolutions of the blue tightening knob. This certainly makes it MUCH harder to pedal (as there is much more pressure on the tyre) but then some Wahoo Kickr Snap users say it’s entirely up to you hard to tighten it? What’s the right way to do this please?

i usually do two and a quarter turns of the knob. the way to tell you have it right is to do a spin down on the wahoo app – you need the spin down time to be between 10 and 15 seconds. if it takes longer, go tighter. if it takes less, loosen it up.
