You're right. I have it currently setup to check for an achievement unlocked prior to the release date. This gives future members a chance to still receive it when their achievements are synced up to the site. It's retro'd for everyone.
I think I should have the one for 5k from a year ago from a competition I was in but no worries as I'm building up a collection of easy completions to get the 10k badge anyway. Just a few more to go and then it's just finding the time to play them all.
I got the single day achievement today, but the weekly one I still do not. Do the weeks run Sun-Sat or Mon-Sun? Either way, I think last week in July this year I should have hit over 5k no matter how you slice the week.
