Reed is by no means a sure thing. Stats only count ~25% weight in admission. I agree with needing to run the NPCs for each school to see if they are affordable.
OP, would you be happy with only one school option (your safety)? If you would be happy to attend UW with no other options then your list is fine (if UW is truly a safety - haven’t looked at the Common Data Set to see). If you think you would like choices then you should add another safety school.
