How to do this Pole Helix

I must be overthinking this… what’s the best way to create this helix-based post? The post tapers as it goes up, making the helix radius smaller as it goes, but the spacing remains the same…


Hm - that complicates things a bit - something like the attached, I guess - make one repeat, copy it a bunch of times and then Taper, Flat=No and Infinite=Yes.

trim to taste at the ends…
