It looks like your not getting any accepted shares.
Has that timing capacitor been replaced on your boards ?

The klondike design is very sensitive with the nor gates and the phase shifter in front of it. It is a matter of the manufacturer of the nor gates, as well as capacitor/resistor. For less HW errors, the Tau of R and C has to fit the propagation and switching times of the nor gate, and these are sometimes higher, sometimes lower, and changing with every type of nor gate. So very hard to make this working properly....

In this case, it would be very easy to make it work by changing the R or C to meet Tau for a particular nor gate.

Exactly, but this is a very empiric process and i think nobody really wants to do this for every new nor gate.

the fact is most people ordered the nor gate listed on BKK's BOM but still nobody has lowered the HW rate to a very low level by changing the Capacitor.
