Is something wrong? Flow Dynamics Calibration k=0.30

Hello, I just wanted to gauge if this is cause for concern or an indication of another problem. I’m getting k values between 0.2 and 0.3 for 3rd party and Bambu Labs HF 95A TPU. I would assume for at least the bambu labs one I should be getting much lower k value. Just wanted to ask and see what others are getting/think. Thanks!
