... but things changed again and again, so I'm sorry about asking yet again.
Thanks to newly discovered decorations, I now have access to six girls with high multipliers. Since I'm allowed to place eleven, though - any advantage anywhere, or is their order totally meaningless? (With the exception, of course, to place one of them in the 11th chair, because of income reasons.) I read something about 'low multiplier in first chair' somewhere, and a lot about 'third chair in tandem with eleventh', but I don't know if that's still a thing. Advice would be appreciated.

Oh and since I'm already spaming anyway: Last decoration cost me 1.something million. Then there was one for 2.something million. Now it's 4.something. Please don't tell me it's a x2-multiplier. x_x Because I'm at 19 out of 23. If 20 costs 4., then 23rd would cost 32 million. That's... insane.
