I think her first reading is always the most accurate in my opinion. It also depends on what time you catch her/her mood. I do feel its hard to decipher if its her all the time as I get a sense of lack in follow up readings and disconnect almost like its her when you first read with her as a new client but then she passes you on (if that makes sense) because my follow up reads touched on the first but seemed more opinion based once she knows your situation. Hope that makes sense.
I would recommend phone over chat.
