Looking around it seems estimates vary by a fair bit, and the one you cite is on the high end. Other estimates are in the low hundreds, which is a very attainable number of reuses. But it does seem my memory was unrealistically low. Also an aspect that is not considered in these studies is that canvas bags generally carry more stuff per bag than single use plastic ones, so taking 2 canvas bags to the grocery store can save 6 or 8 plastic bags.
