Really only TNT or n_t would be able to tell us that at this point. From one of n_t's earlier comments:
1/10 chance to run the stock algorithm,
For each one, ((101-stocked)/100)2 chance of stocking.
So if 99 have stocked, it would be 0.022 = 0.0004 (0.04%) chance of stocking. compared to if 90 had stocked, which would be 1.21%. So fewer items left means a less likely chance of stocking.

From the JN page, there are 63 smugglers cove items, so that would be 630 items stocked.
