When I checked, which is a year or two back now, I found similar problems (I didn't get hard figures but I had the feeling it was a lot higher than 12%, but then I wasn't conducting a rigorous survey). Conversely, I found that if you just ploughed ahead with P-256, things usually worked. This is what motivated the use of P-256 in -LTS, it's the de facto standard curve.
