@Fenris477: Jack of all Trades & Remarkable Athlete add the tag Helper.ProfHalf to the skills at post-level 10000. The timing of my example is set at the same time, so I suspect it would be better to run the proficiency adjustment earlier than Post-Level 10000.
@Mergon: I forget about the adjustments, but I see ShadowChemosh put his in during the First timing phase. ALSO, as a disclaimer, I don't use the community files so I forget to look at them unless I hit something I can't figure out after fooling with it for a while.
End of day, should probably run it when ShadowChemosh puts it in timing although in my mind there are some reasons to run it post-levels (maybe at 5000).
