	How do you come to this conclusion?

	My main purpose in using cardinal information is to incorporate
preference strength into defeat strength, and thus to protect defeats that
consist of many strong preferences. Using cardinal information in addition
to ordinal information also tends to allow voters to engage in effective
counterstrategy without altering their rankings, which generally leads to
greater stability in strategy/counterstrategy scenarios. (This second
reason is shared by methods like AERLO/ATLO, S/WPO, etc.)

my best,
