That's correct: it's been added 151 times in collection (making it the 145th more collected LD).
It does account for multiples: if 3 titles have been added 151 times in collection, they will all appear as the 145th but the next title to be collected, say, 150 times, will be listed as 148th, not 146th.
It was added only once to wishlists, making it a distant 5,737th.
