With the first version of CW2, I know that it was not possible for you to know when the clan finished the race.
So, it was difficult for us to know if the user is active during the race or only during the days after the finish line.
We wanted to know that to manage our members : I took a screenshot when the boat finished the race and like that, I had a history of active players only. The battles after the finish line were not useful for the clan.
Today, with the update, I think it could be possible for you to upgrade RoyaleAPI to meet this request because the switch from training to battles is defined and the same for all clans. (I think)
So, is it possible to have a distinction between the decks used for training (Monday to Wednesday) and those used to move the boat forward (thursday to sunday)?
For example : If, at the end of the week, a player used 16 decks during the training and another used 16 decks during the race, this is not the same thing for us, as clan leaders.
In the past, we had that type of players : they only played after the finish line. They seems active in wars in the stats but they are useless for the progression of the clan
