Allow users to set their own pessimistic presumption on Do Less goals
Right now you can make a Do Less goal and "pessimistic presumptive" is turned on by default. If you do not report your data, Beeminder automatically puts in a pessimistic datapoint on the days you missed, which is usually around x2 more steeper than the road.
My suggestion is that this rate be customizable so that it may be more pessimistic than just x2 the yellow brick road.
For example, a person may have a "Go to bed early" goal, where he/she aims to sleep by 22:00 (10PM). You create a do-less goal where you report -5 if you slept 5 minutes early (21:55), or report +5 if you slept 5 minutes late (22:05).
Say you've dial the road to 5 minutes/day to give yourself some wiggle room, and if you sleep early for long enough, you can have a "cheat day" of sorts. The pessimistic presumption in this case is somewhere around +10.
The problem is you can easily have a cheat day any day. One can go to sleep really late on any day, say at midnight (+120). But if you leave your Beeminder graph alone and let the pessimistic presumption put in the datapoint for you (the +10), then you are probably not in any real threat of derailing anytime soon. And +10 is way better than +120, even though that's essentially fake data.
But if it were possible to set your pessimistic presumption, say x30 your yellow brick road (in this case, +180), that can give someone a real kick in the pants to report their real data.
Pessimistic presumption should always assume the worst-case scenario, but in some scenarios it simply doesn't manage to do that. Giving users the ability to set their own pessimsitic presumptive should fix that, because users can then set their own worst-case scenario.
