Can I get rid of extra safety buffer?
First, think about whether or not you've already entered data for the day, to make sure that you don't accidentally set yourself up for failure. It's not great to remove all the safety buffer on your calories goal right before logging your big birthday dinner, and it's not great to remove all your safety buffer after you logged your 8-mile run! If you do accidentally back yourself into an emergency day corner, contact support and we can undo your adjustment.
Then, in the Safety Buffer section of the Commitment tab below the graph on the goal page, pick the number of safe days you'd like to end up with, and click Retroratchet! to save changes.
This feature may be limited if your goal derailed recently, in order to prevent you from unintentionally triggering a second derailment. (Our bug, not your fault!) Contact support and we can do it for you!
Automatic buffer removal
If you're a Bee Plus or Beemium subscriber, you also have access to an automatic retroratchet (often referred to as autoratchet), right underneath this field. To enable autoratchet, check the Automatically trim safety buffer box next to Max Safe Days, then select the highest safe days you want to allow yourself on this goal.
Every day at your goal's deadline, Beeminder will check the number of safe days on the goal and remove extra safety buffer if necessary. With the setting shown above, if I ever have more than 7 safe days at my deadline, Beeminder will adjust my goal road automatically to remove the extra so that I only have 7.
