"Perfect Week" achievement is broken?

Is there a trick to getting the "Perfect Week" Steam achievement?

I've completed the daily challenges for 8 days in a row now. My progress has been showing at 57% complete for 3 days.

its a long shot, but did you do it Mon-Sun? or more like Wed-Tue ?

I probably started mid-week, I don't know exactly which days. Perhaps if I keep it up the achievement will pop at the end of this week.

Been wondering the same thing

@Skrubby, maybe it is Sun-Sat or Mon-Sun. The achievement wording isn't clear about the terms.

Now I'm on day 9 of completing the challenges each day. Today the percentage increased to 71% after being stuck at 57% for 3 days:
