Part of the reason why they're currently placeholders is those sizes aren't intended to really be hit at this point in time. Have been working on the next update adding in the second prestige layer, which should considerably speed up the progression to allow those sizes to be hit. That being said, I am also considering doing more in betweens regardless. But put those there since I figured it would be good to have the coding for that done first and have placeholder stuff to remind myself to fill it in once they're more achieveable.
