I've had both email and phone with her and her predictions always stay the same, just that with phone you can ask her more follow-up questions and with emails her thoughts flowed better I feel. I think initially her emails were easier to follow for me but now I feel even her phone readings are quite clear too, not sure If she is just more intune with me as I have read with her a few times.
and I will also add that she has been the ONLY reader who has made predictions on how my POI would act/say in the future which actually happened. this was not very typical behavior of my POI but this is something I wanted his to do and he did. I was shocked, to say the least.
