resteal here?

I joined the table about 20 hands ago. Since then villain has been folded to in MP-LP 3 times and raised all 3, winning the pot uncontested, twice to 4x bb, once to 3x bb. Am I correct in thinking I have enough fold equity vs his range to resteal here? (I have no idea what it is, but from my small sample size I'm assuming quite wide)
