Anyone use an implantation dip on BBT chart to begin testing?

Has anyone used an implantation dip in temp as a signal to begin testing for faint lines? This is my first month of charting temps. I see my corpus luteum dip on my chart, but curious about accuracy of implantation dip since it can apparently show on non-pregnant cycles as well. It seems like it would be a useful indicator to begin testing a few days later. Thoughts? Experiences?
