You won't get more than
two chains per cassette however.
Another case of "your mileage may vary". I have over 18,000 miles on my DA cassette and its 5th chain. This last chain skipped a bit on the 17 until it wore enough to break in. The new cassette is in the drawer waiting for the next chain change. It's going to cost to ride a bike. I'm over it.
