My DS applied to 12, ED1 deferred, accepted ED2, accepted at 5 others EA and rolling before the ED2 decision, 5 others pulled after the ED2 decision so a lot of them turned out to be unnecessary.
Even without the ED acceptance, he should have probably only applied to 9 or 10 at most. A lot depends on how well you identify targets and safeties as my son was focusing on Top 30 to Top 50, although he applied ED to 2 of them because he really liked them and they have low acceptance rates.
