Ok Far as Archery goes I went into Abyssea and test with stacked regain atmas. With the exception of Blast Arrow here are the following maximum distances in yalms.

Sidewinder 16.5 (tested this several times just to be sure)
Empyreal Arrow 17.7
Refulgent Arrow 17.7
Arching Arrow 17.7
Apex Arrow 17.7
Flaming Arrow 17.7
Piercing Arrow 17.7
Dulling Arrow 17.7

I'm going to test marksmanship as well but it's probably safe to assume they're the same (i.e.: Detonator = Empyreal Arrow, Slug shot = Sidewinder, etc).
