...The resistance you select or target for your build determines the heat energy output in (W)atts based on power in (V)oltage or Amps supplied by your battery or variable power device. These are the two things you have control over Res and Watts (a range).
The Mini I think is rated something like 7-30W. After vaping it along with the Sub for a bit now I'd say the sweet spot is likely somewhere in the middle, between the 15W I posted the pic of earlier and about 20W. Let's call it 18 for ha-ha's.
Take a look at
Coil Toy - Online calculator for e-cigarette resistance coil building and consider .8Ω as a target which is the sweet spot for a great many of the APV's out there (broadest range of power delivery),
Ohm's Law Calculator should tell you if that 18W target is consistent with the output of your APV. Check that vs.
Mod range | Steam Engine | free vaping calculators to see how your mod compares to the power requirement. Plug in your resistance in coil toy and vary the wind diameters to see your alternatives. I can tell you the internal post spread parallel to the coil is about 2.2mm, overall 3.2 end-to-end.
