Yes, I found the goal that will benefit from the extra accountability for the No-Excuse challenge: tbr_pur_pages_stale. It’s also about reading, specifically a whittle-down for the total number of pages in the books in my TBR, where the number grows exponentially as a book ages (x2 over a year’s time). This should encourage me to read earlier acquired books and to think twice when grabbing new ones (ARCs, library, books on sale). If I post how the graph looks right now, an apt eye will see immediately the 4 spots where I… ahem… made excuses instead of legitly derailing.
And from here, I will hide the past period and start the year with the extra accountability from this challenge. Legitly derailing and adding allowances for the future, acrasia horizon respected, is allowed. (And this creates a loophole of how quickly the books should be processed and accounted for after acquisition for this not to be cheating by not entering the pages into the database. I think within 24 hours should be reasonable - unless it’s a “read now” for a limited time or a library item for which my turn came, so I have to grab asap but am too busy to immediately add all the tags by which the code pulls the titles from goodreads etc. - then by the end of the week should be okay. @shanaqui I remember you had some really good thoughts on a similar matter - was it in your journaling thread? IIRC, it involved accountability to your partner? I am thinking of how to avoid a slippery slope here.)
UPD: so, in normal circumstances, I should process add all the books to the database within 24 hours. But because this year I will have an extremely uneven workload throughout the week, I am leaving the possibility that, if I had to grab something in-between other stuff, I must absolutely process it when my less busy part of the week happens, which by definition will be within acrasia horizon (or, if missed and that addition would have caused a derailment, backdate a datapoint to enforce a derailment).
