I was thinking about that too, I think it's more at day 50 and has 2 weeks to go, maybe more
EDIT: reason why I think that, is many breeders say their days-to-end-flower is X days after flip but there's a duration of time for transition s/he doesn't include. Let's say a grow begins:
Day 1 germ; Day 50 flip; Day 60 end transition. Now begin flowering day count at day 1. I might veg the plant 5 weeks or months but I'll start the flowering day count 7-10 days after flip. If all of a sudden there is a proliferation of flowers, start the flowering day count. This works for me maybe not someone else.
