Agree with others that the assessment hours are on the low side. Most of your peers will have 50+ and many will have 100+.
If your 3 integrated reports are super complex and can show a combo of Weschler & MMPI type comprehensive reports, that would be better for 25 hours. But if your 3 integrated reports are more like more formal intakes, that's won't play well with assessment heavy sites like AMCs (but glad you are getting that experience now).
Based on your program rates and your hours, if I were you, my total # would depend on types of sites I'm applying to (AMC vs college counseling for example.
If you want 'flagship' AMCs/VAs/brand name sites like Mayo Clinic, your stats likely fall in the lower half of the applicant pool depending on how competitive that site is so I would apply to more and increase your odds of getting interviews.
If you're primarily applying to regional/rural AMCs/VAs that typically go into Phase 2, 15 should be enough, especially if you've selected well for fit.
I don't have much insight into community, prison and college counseling center placements but I would think that same logic could apply.
And if you're primarily looking at matching somewhere and are open to a variety of spots, 15 should be enough as Phase 2 has lots of great programs last year and I would imagine you'd do fine and maybe even have more competitive choices if you ended up in that spot. Good luck!
