Thank you so much for your reply.
The mod page on nexus states that the Realistic Ragdolls and Force mod is not compatible with body mods so should I just delete the plugin and wait to acquire it through the STEP patch? Or should I download the main mod and let it be overwritten by XP32 Maximum Skeleton extended?
Regarding Xenius character enhancement I do not see that mod in the guide but some notes near the top mention it has been removed in favor of other mods. In section 2.H After better males I installed the dimonized UNP body followed by Real Girls Realistic Body Texture for UNP, Better females by bella natural edition, the eyes of beauty and seductive lips. Are any of these redundant or conflicting? Do you think Real Girls Realistic Body Texture will resolve any neck seam issues? I did not install the Windsong Skyrim character overhaul as it clearly states on the mod page that it does not work with UNP or any other body mods.
Further down in section 2.H I added KS Hairdos - renewal after superior lore friendly hair. I also added ShowRaceMenu Precache Killer to prevent crashes caused by KS Hairdos but after reading the mod page on nexus again I noticed it said that its wasn't necessary if I already have RaceMenu installed which following the guide I do have. So I guess I can delete Precache killer?
Finally in section 2.I I installed the book of UUNP with the patches for UNP without HDT and the WAFR and CCOR patches and I am slightly concerned it may conflict with Rustic Clothing based on the mod page on nexus.
And that is the extent of my deviation from the STEP guide otherwise I have followed it exactly. Except I did not download Lepidoptera Of Skyrim because it is no longer available. But I don't think that will cause any issues by its absence. Of course I will not include a LOOT meta rule for it either.
Again thank you so much for your guidance. It has always been my dream to play fully modded skyrim since my days as a console peasant but it always seemed too daunting a task. Your guide is simply fantastic (and those amazing GamerPoets videos on youtube).
P.S. As I've said I'm following the guide as close as I can and have been installing all the textures at the resolutions recommended by the guide. However I have a pretty good rig (I7 processor, GTX 1080 TI, and 32 gigs of ram) and I am curious how hard I can push my machine. What do you think I can reasonably get away with while still having a playable game?
