Depends on the college counselor's capacity, honestly.
DCUM is probably not the best source for feedback unless your area is full of hypercompetitive, highly educated, high-income parents. (I'm one. Not judging, just describing.)
Plus most parents have no idea how admissions actually works in this century. Basically, you've got better odds at blackjack than at selective schools.
FWIW our independent with 65 seniors went from 25 apps max last year to 15 this year using the Cialfo system. Zero input from parents. We still got a crap counselor with no real guidance and bad tech skills and can barely use modern--post 2015--systems.
DC applied to 11. 1 accept (the "safety" we found without counselor turned out to be top choice

), 1 waitlist, still waiting on 2.
The number of applications shouldn't matter. Some kids will want a wider net than others and that's fine. Just make sure the counselors actually know what they're doing.
And use the NYT self-ranking tool.
