I have a question about the subject in the title. I do not understand if as BB we have to consider the % of defence as a percentage of the button's open raising range or not.
An example: If I have to defend at least 33% when Button try to steal, I have to consider the 33% of 40% or my 33% is an absolute frequency?

Thank you, I am struggling with these thoughts but probably it is a very simple question.
