Is 主観 actually high-yield or is my Phase 2 deck lying?

On Day 45 of my Vocab Optimization Routine (Phase 2), I scheduled 主観 for a 4-second recall interval. Step one is memorizing 'subjective view.' Step two is finding native context. But my daily 90-minute immersion block is yielding zero hits for 主観. Is this word actually used by normal humans or is my SRS algorithm feeding me low-yield garbage? I need to know if I should purge it from my active queue.
