The Mega updates are what I refer to as the poll winners. Basically, you may have noticed a substantial jump in how much extra content was written for Sara in contrast to when Clara had her update when I first came on-board. Clara was only updated for about 5500 words which was sort of a tester trial for my writing and to gauge the reaction. Sara's script however was over 10,000 words. Nearly every update I write now will be double the size of Sara's at 20-40K words. HOWEVER, the Mega scripts will be 40K+ for each of the Poll winners. (Tiffany,Mary,Becca and to a lesser extent Clara). So essentially, every proper update (Not just technical overdrafts) are going to be minimum 2x as long as the previous update or even 3 to 4x as long, but the Mega updates will be the plus extreme end of the spectrum.
NOTE: This does not factor in how much Uberpie is able to manage, as the scripts are becoming increasingly long, I can't guarantee this won't cause delays in the future for obvious reasons. Especially given neither of us can commit full time etc, but by that point we'd probably be able to hire someone else to take some of the work load.
