Is HRC (Holdem Resources Calculator) decent for basic cash preflop solves?

I heard they've improved their algorithms recently and I'm wondering if their solves could be considered good enough to get general concepts from. I'd like to solve some more unusual situations / inputs, limps, cold-called 3bets, unusually large or small raises pre, etc (and yes I know all this is very villain / situation dependant but I'd just like to experiment a bit and trust the output isn't on another planet)
