blind defense question.

[cdxx]

how do you use stats to figure out when to defend and when not to?

for example, in the following hand MP has 42% attempt to steal blinds. BB is 50% fold to a steal, but also 50% fold on every street, so if i am reading that correctly, he can be pushed off a hand. i am thinking i made a mistake just calling pre-flop. (comments about post-flop also. i know i suk)
