Accusnap accuracy

Hi, would I be correct in thinking there is a problem with Accusnap accuracy?

Apologies for starting a new discussion on this subject, but I had been using version ok, and now I have version and I'm experiencing a very wayward Accusnap, i.e. zero accuracy.

I did follow the advice to max out the accuracy settings, but it's still very much hit or miss.

Any advice/guidance would be very much appreciated.

Cheers, Andrew
