This goal has the following fine print specified by coolhandlouis:
I want to accomplish this goal every day. However, I'm only going to be responsible to beeminder to complete this goal once every 5 days. While this leaves me an "out" to drop my performance, it aslo reduces my beeminder pressure, which reduces chance of beeminder burn-out.
This is an experimental goal. "DAYOF" means I only track the goal on (the "day of") it's beemergency due date. I still endeavor to complete the task on other days, but that's entirely outside beeminder and I do not increment on those days.
I'm trying to figure out if it's ok to OPTIONALLY mark a off-day as "done +1", or perhaps even retroactively mark an off-day as "done +1". I'll need to iron out the details to ensure that I remain on the good side of beeminder paradgim, non-weaselly, no fake data, etc. OTOH, it's a little complicated, and just sticking to "only increment on beemergency day" is a paradigm-safe way to manage this.
I think the following is paradigm-safe: OPTIONAL data entry on any day. If I want to kick the beeminder can down the road, I can. For example, if it's beeminder 1/5 days, then the presumptive schedule is done on day 5 and 10. But if today is the 4th day, i can mark it done and kick the beeminder can down to day 9. I've only shifted my 1/5 days to a little earlier. This is best managed with an auto-ratchet to 5 days.
On the other hand, I don't think I can easily retroactively mark yesterday as done if today is a beemergency. That could effectively create the same schedule such as on day 5, making the schedule be done on day 4 and next beemergency is day 9. However, the auto-ratchet to 5 days may not work in some situations, and it's a bit weaselly if i retroactively kick the can down the road and also don't complete today's beemergency task. Even though it's no different, it doesn't feel right.
