Apologies, but this is in fact the opposite of the advice I gave. If you get a forward collision warning on a low-km day (so low that your FCW penalty is capped at 63.3), you should park your car, not drive it again that day, and get in lots of clean kilometres the next day.
Remember that days are weighted by kilometres driven. Counterintuitively, a low-km 41 day may have less negative impact on your overall score than a high-km 97 day. Waiting until tomorrow to have a high-km 100 day will do the most to fix the problem. Think of it this way: if by waiting one day you can add 116 level-100 kilometres to your average, isn't that better than adding 116 level-97 kilometres to your average today?
If you want to prove this to yourself, you can play around with one of those safety score calculators you can find on the web.
