I have a question about the timers/foraging points

Are these cumulative? As in, for my first journey, there are some days I dont have enough space to carry extra parts/reagents, so my scrounging time has been above 0. Do i get to add these times from day to day, or is it based on that day? Asking because I see Satchel, coat, blanket have hours that seem to exceed what I normally get if i don't treat the timer as cumulative.

As for foraging points, do we gain foraging points only when it's Too Low and does not exceed/equal the difference or BR? Does that mean the FP is then added on to other days in the journey, or will it be the same unless we spend it?
