With the iron I'll make you all flat broke. Ohohoh...ahah..aa..er.yeah lame, I know.

The obvious reason the "read each chapter as it comes out" option won, is because the reason that most the mangaupdates users use this website, is to check for the releases of their favorite series so they can read the chapter when it comes out. If people really didn't care about when it's released and rather wait are probably the people who aren't even users of mangaudates right? So in a way it's slightly biased. But it really doesn't matter.

BTW I'm a "read each chapter as it comes out" person. I'm just too impatient to wait when I can read it when it comes out. If I did wait, I'd probably have withdrawl symptoms with lack of manga. XD
