Reflect spell question

[Chicken Slayer]

Can someone confirm this for protections...Weakness to magic (e.g Apprentice birth sign) is additive to Resistance to magic (Breton/Orc/Mundane ring, etc). So a normal 100% spell hitting 100% Weak to Magic + 50% Resistance to magic = 150% force affecting body. Now, that 150% spell encounters Reflect Spell (e.g. Spellbreaker shield 35%) and is still reflected 35% of the time (correct?-unaffected by WtoM?) and then the spell (if it gets past the reflect) hits Absorb magic (e.g. 20% amulet) and is absorbed 20% of the time (correct?). The result would be that someone with Apprentice birthsign would need 200% resist magic, 100% reflect spell, or 100% absorb magic for full protection in a fight (correct?).
