Actually Russ, the reason I mentioned it is because he specifically
provides forecasts for MW and LW; the MW forecast is the one I reproduced.

Probably of limited applicability as it mostly orients itself to SW
and VHF. While it includes what hams call "LF", which correlates to
160 meters, which is located above the MW BCB, the propagation
characteristics aren't identical.
The bottom line with almost any MW propagation forecast is that
predicting what's going to occur with the sun is iffy at best. Many
large sunspots remain active through 2 or 3 solar rotations, which
increases predictive accuracy, but new spots forming on the back
side of the sun or other less visible and less predictable impacts
can come from other events. Further, some events occur but are aimed
away from earth and therefore have little or no impact.
