This means more positions near the "tips" will be stored in the table and will remain there, increasing the likelihood of getting a hit out near the leaf nodes. As the table size shrinks, shallow draft entries (near the leaves) get overwritten by deeper draft entries (near the root) and they won't be hit as often. <HT> simply means the PV was cut short by a HashTable hit before searching to the terminal node that produced that specific PV.
