O.K Looks like your ACH is a little high for a total SPF home. Not crazy but also not quite as tight as we design to. We design to 3 ACPD. Also I noticed in the photos of areas where the foam is pulled off of the wood joists. This is usually an indication of misapplied foam at the wrong spray temps and or mixture, or they were spraying onto a cold substrate. But believe it or not, it does have a dramatic total installed effect of the SPF hence the efficiency or performance factor drops.
