Yeah I think if I remember correctly depending on conditions and precip intensity ice accrual ranges from about 28% to 50% of whatever liquid falls. Someone can correct me if I am wrong but I have seen that in a paper on the topic.
I was at Hanging Rock by Moore's Wall and they got hit pretty hard. I would say max ice totals of around 0.5-0.75 inches with 0.25-0.4 a little lower down. It varied quite a bit depending on the exact terrain etc. Pics to come.
