I may appear to be being deliberately obtuse here (because I am

) but if there's no definition of what would count as complete - then it's not really a challenge. If finishing with 12 points isn't completing it - what is the lower limit? 13?
And most importantly, do I get a star or other badge? And what does it look like
By being so negative and carping on I'm actually trying to be helpful and possibly improve it.
Here's where I'm coming from. Various challenges on here have been tremendously useful motivational tools for me over the years:
I simply have to get out on the bike tomorrow or I'll be out of the challenge (whatever it is). The lunacy challenge waters that motivational power down a bit by allowing you to skip months and then catch up, but the overall target of 13 is enough to get you out of bed. I'm not really seeing the same motivational power in this.
Without some kind of lower limit or a pre-declared personal target (like the luncacy challenge has) or something like that it would be easy to cruise round without trying very hard, and with little chance of failing to finish, and pick up the shiny badge at the end.
