The training status through my 935 is fairly accurate in terms of what it recommends for recovery (taking note that it will say train easy or as usual with time remaining, as noted above). After a hard running or triathlon race I get a long recovery period which makes sense. The actual training effect numbers don’t always seem to make sense nor does the training status chart though. Also, I’m “Unproductive” A LOT! 
I think it only really shows Productive if I’m increasing my VO2Max which of course can’t happen all the time (and the race predictors from the VO2Max scores are incredibly generous as well 
).
