OK for the lazy, here is the original thread:

And here is my summary of her performance posted in that thread:
Now there could be an explanation why she is not completely clear on her record: HFs can not advertise and going on a show and touting her record would count as such and she could be fined. By the time she was on TastyTrade, she already had enough money under management, so I don't think she cared about getting more... Just my projection...
Most likely she never had a better than 50% return, specially not with the HF. It would be interesting to know her record in the last 3 years, but I couldn't find anything on the net when I looked a few weeks ago...
