1 1/2, they got jacked up pretty bad from what I can tell. Not sure Jon's will make the trip or be very useful if he does. Also not sure of heal time on a dragon.
They have made it a point to state the Golden Company has never broke a contract. They also have never fought against dragons so who knows. It would be poetic license if the Golden Company turned on Cersei at the last ala the Gold Cloaks turning on Ned in season 1.
Kinda my point. Since the books ran out, the writing has taken on a much more Hollywood feel to me. There was a distinct cut line for me when you could tell the books where no longer supplying the detail for the screen. I know they've taken liberties with the plot lines but for the most part didn't deviate a huge distance from what the books laid out. I think if the series had been complete the Battle of Winterfell would have produced a decidedly different list of survivors
Ultimately I guess you're right, who cares? Just my opinion for the book crowd I guess.
