Why not Conquest/Breakthrough 96 or 100?

Someone explain this to me like I am 5.

128 or 64v64 was said to be too many players for Battlefield, so they rolled back Breakthrough to 64 only and Conquest 128 is the only mode with 64v64 left.

So why is there a need to double the player counts? Why not meet in the middle and do either 96 (to keep full squads) or 100 (so they can get to that magic number for marketing)?

With 32-player teams, you have 8 full squads, with 48-player teams that would give you 4 more squads. 

OR

Make 5-player squads and go to 50 v 50. 

It just feels like the player count is always off, 32v32 is not enough, and 64v64 is too many, so why not compromise and meet in the middle?

What am I missing?
