Yes the system predetermines the strength of a clan before the star war button is pressed, but when a player who is part of the algorithm leaves, the system quickly recalculate... when a clan is one less player from required member, ex. 1 leaves from a 20 clan, the system automatically scale it down to 15...
Please use common sense before replying, and please realize you offered no solution.
