I didn't apply to any safety schools really (only PGR top 25), mainly because how risky it is to do a PhD in philosophy anyway in terms of finding an academic job afterwards. My letter writers also discouraged me pretty strongly from applying to safety schools. I think that this approach has made the application season more anxiety-inducing for me (trying to have very low expectations), but I also feel like it made sense to spend my money on applying to more highly ranked schools given how unpredictable the process is
