With regards to EPS, if the foam is compressed from impact, it should be replaced in case you impact the same spot again (protective qualities compromised). Not just the case of a cracked helmet (I'm certainly not telling you what to do though).
That said, yeah, my events have always been either OTB or really abrupt slide-outs. Both those scenarios involve a very small likelihood of front-rim impact. I'd say that's road/commuter data, for a large part.
