No, this isn't another 'FOC figures are tiny' thread. I've only been collecting sporadically since the first movie toyline, but something I've been curious about for a while is how much of a discrepency there can between two figures in the same size class and toyline, despite each figure presumable having the same plastic budget. For example, Prime Deluxe Knock Out is pretty small compared to his wavemates in vehicle mode, even though some parts compression and lack of major kibble allows him a fairly tall robot mode, but then you look at Wheeljack who is honestly on par with the First Editions in both modes. Over in FOC from what I can tell from pictures, Shockwave and the Combaticons are all a good bit larger than Jazz and especially Optimus. And while I don't recall exact comparison from the movie and Animated toylines, I'm sure there must have been some examples from those with notably different sizes. Anyone know how this works? Is it a case of having a total amount of plastic allowable for each case, and a maximum amount on each individual figure which they use for some and not for others?
