Progress survives bad days when the standard includes adaptability.

Bad days are not exceptions to be planned around. They are a permanent feature of any long effort, which means a standard that only works when things go well is not really a standard. Building adaptability into it is not lowering the bar. It is making the bar something that can survive contact with your life.

Write down in advance what this looks like at twenty percent capacity. Decide now, while you are clear-headed, so that on the hard day you are following a plan rather than negotiating with yourself.
