Depending on the gauge of the wire used,1 or 2 turns is max to achieve ballpark ohms target,hence why sometimes its a bit diff. than what advertised;if its a big gauge,a mm or 2 can lead to a 0.1 or 0.2 ohm diff.
So,if those are low res,2 wraps is std. specially if it has to wrap around 2 wicks.
I see 4 there,so lookin good.
