I'm just trying to make a point that it is OK to ask for verification if someone is making claims about their system being 80% profitable.
We all have limited time and we've all been lied to, misled, and have wasted time. So if he's putting his system publicly out there and making an incredible claim such as 80% then, it should be OK to want to verify it. This is not disrespectful, it's just taking an interest and wanting to see the magic of 80%. Anyway, the highest I've personally seen is about 74% with my own trading.
It takes money to make money.
