Rick, That is true if you want to assess NA propagation, but if we are evaluating “real” DX from NA to EU, OC or AS, then we are listening on the 9 kHz DX splits not the domestic 10kHz offsets. Conversely, those in EU, OC and AS will be using the NA 10 kHz splits to assess propagation.
Personally, here in VE6, unless there is a severe Geo-mag storm, the 160m band is open coast to coast virtually every night.
