Patience Sushi,
The assay results may be this week or in a week or two. Whats the rush, the longer it takes typically the better the grades.
Regarding the POS, IVR have not proved a resource yet. When they have, POS movements should start to correlate more closely with the IVR SP movements IMO.
In any case, with the big seller adjusting the SP, you are unlikely to see correlation for now.
