That's the one that was reset on purpose.

Here's my code:

#(Number of total challenges I've done)-(Letter denominating year this is in)(Number of stories this year)

If you go far enough back into my archives, which is a deep dive because this is my ninth year doing this, then you'll find entries where it's just the first numeral. That would be my very first Year of Instants... all the way back in 2013.

Thanks for the vigilance, but it's all the future ones you need to look out for.
