I've had my Spathiphyllum wallisii for three years now, and I'm still figuring out the watering sweet spot in my dry climate

I've had my Spathiphyllum wallisii for three years now, and I'm still figuring out the watering sweet spot in my dry climate. Everyone says they're dramatic and will tell you when they're thirsty, but mine just droops *slightly* and I second-guess myself every time. Lately I've been letting the soil dry a bit more between waterings—not bone dry, just to maybe two centimeters down—and it's actually thriving. Fewer brown leaf tips too. Has anyone else found their peace lily prefers less frequent watering than the guides suggest?
