I am an undead rogue with 15% guilds (80-100% BE) since age start. I only casted self spells and a few ritual spells. 47 out of 58 self spells are succesful. That is 81%. I am even failing simple minor protection spells...:S can you check if there is something wrong? I would expect a success rate on self spells of 98% or higher. (I am not human ;-))
