Second of all if you start pushing the issue villain might adjust to your overaggressive gameplan. First of all, you need an adequate sample size to determine if fold to steal stat is even reliable. In practice, it's obviously a bit more complex. This means that if certain players fold to steal stat is higher than 62,5% you can steal with any two cards. If you do some quick pot odds calculations assuming that your BU preflop open sizing is 2,5BB and SB sizing is 3BB you need roughly 62,5% fold equity for your raise to automatically show a profit in the long run. Fold to Steal is very useful when we decide how aggressive our preflop BU and SB game should be.
BB(SB) Fold to Steal When the BB(SB) faces a raise from either the CO/BU (or SB) and they fold.
