Not quite as extreme but when I was off for months due to a stomach op my calendar was full of red but further into the season and with more consistent training more TSS weeks were green (white).
I suspect if I had used TN at the time it would have looked at the initial period differently and suggested I upped things to improve (which I gradually did). The reds were just a ‘knee jerk’ RLGL reaction to the complete lack of training but I actually gradually needed to do some to improve. TN is maybe trying to improve you a bit faster but come back in your own good time and stay healthy
