Actually I think that is really a 12a pulse the SureTest uses and I question how accurate that short pulse really is in predicting voltage drop. I would love to borrow one and look at the pulse on a scope to see what it really looks like. For that matter I would like to verify the result with a volt meter and a hair dryer.
I guess it is still not important. They will still be writing these things up on their report along with other "hazards" like "double tapped" QO breakers and calling out old tinned copper wire as "aluminum".
The bottom line is these guys are not enforcing code, they are trying to give buyers a bargaining chip. I suppose a few of them will have to get sued by buyers before they back off.
