Slick Willy changed how UI figures are publically reported. 10% is his way. 17.2% is from the old way. To be honest about the numbers, the only method possible is the old way, to remain consistent and reliable over time. Even though the government purports both ways to be equal, those who know both methods know better.
17.2% is the only accurate figure out there. Only those who trust govt rely on the govt's politically-expedient ways and their 10% at this time. Any of those people left?
Keep in mind that neither method includes workers who have given up looking for work, and those who do not qualify for UI benefits.
A realistic guess at this time is 22%. Just a guess.
