It's below 0.1. Never had the ultra sensitive test. One time my PSA was tested at a lab with a low threshold of 0.03. My PSA was listed as < 0.03. At 1 year out from surgery I requested being put on a PSA test schedule of once every 4 months instead of every 6 months. At two years out I requested to be tested twice a year instead of once a year. My Surgeon/Urologist had no issue with this. Sounds to me like your PSA results have been excellent.
