In the 1st hand, did you set the minimum edge to what you think your avg winrate will be on the next hand if you fold (in this case substantially negative)?
Yeah I set it to a negative edge but tbh I'm not really sure how to work out a valid number for this. What would you consider to be substantially negative? -0.25%? -0.5%?
Any further explanation as to how to work this kind of thing out would be greatly appreciated

Hands are here if that helps:
