FYI: I've never participated in a community challange here before. Having only bought my first Xbox a few months ago and missed all the ones since. So forgive me for asking what might seem rather stupid questions, but I want to make sure I didn't misunderstand anything in the description.
1. "TA Ratio" means the number that shows up under "RATIO" when viewing eligible achievments and other achiement list like it? I should effectively start with a very easy one and work my way up with the smallest increments that are at least 0.2 higher possible.
2. Once I've finished Day 11 I need to manually scan again or wait for the next automatic one, if I've used all. Then I'll get a "Start Challenge" button. As long is I don't start the challenge officially, I can unlock as many high ratio achievements as I want after finishing Day 11 without having to worry about making the challenge impossibly hard.
3rd question while I'm at it: Where exactly on my profile are challange badges to be found? If I win this one, do I need to enable it for it to show in my profile or in the Forums? If yes how and where?
1 - Yes, try and start with the easiest achievement you can find with a ratio close to 1.00, then work up so one around 1.2, then 1.4 etc
2 - Once you've finished day 11, go to the hub page and click the start button for day 12 when you're ready for your next achievement you pop to start the ladder
3 - Your badge will automatically appear on your profile homepage
