yes, i've had psychics predict things that did happen, that i didn't think would happen. Even recently my top three predicted somethings that ended up being true. Timing may be off, but i don't hold people to timing, but the predictions have been accurate.
"they were right about this, but wrong about.." that will be with any psychic, no matter how good.
75% or better is pretty good, they all average more. Some things predicted, there was no way it could have been guessed or a lucky, they were something very specific.
I had a psychic i read with 20 yrs ago predict things, i'd say 75% of what she saw happened. She was excellent, i just stopped seeing her because she started to project her own opinions instead of reading. She wasn't like that at first, but over the years she was lecturing on top of reading, and it was too much for me.
