I have used this software on MSF on 60kHz as a means of manually setting
my PCclock, I have not tried it on the mode that electronically sets your
PC. There is obviously no timing errors or enormous errors with this manual
method, depending on your interpretation of "accuracy".

It is also worth looking at the same site for their "Beaconsee" software
that checks reception of the NCDXF HF beacon network and indicates in real
time the HF conditions. It also has a nice map of the world with real-time
darkness and daylight footprints.
