Does anyone know how accurate these are and if the test line is meant to match or be darker than the control line like the normal tests?

Thursday at 1pm I had a positive digital but the test line was a lot lighter than control line. Normal test was almost the same as control line and was 0.96 ratio on premum app.
Scan friday at 12pm showed follicle still there but squiggly around the edges. Scan today at 11am was basically the same, so 46 hrs after the digital said positive.
Ive just tested again and the digital is still positive, with the test line being almost as dark as the control this time.
Given today's Scan was 46 hrs after my positive digital and I still have an intact follicle, I'm wondering if the digital was actually wrong seen as the test line was a lot lighter than the control line, and my surge didn't actually happen on thrusday, but could be happening today now the test line is darker on it.

They are accurate in the sense that they will have detected an LH amount above the threshold to constitute a surge. What your body then does is its own affair. You may have ovulated but the corpus luteum wasn't yet visible. Or your body may take longer than 36 hours post surge. Sometimes there is also a second surge.
