so when would you say you "started" doing youtube? you seem to have created the channel on feb 17, 2012, but it seems like you hadn't posted there until september 2013, when you uploaded a few vids you made months or even years beforehand. then you seem to have sorta went inactive until 12.29.13 when you uploaded many more vids you made before, then shortly after, you made this website, started the 5 day schedule in the beginning of feburary, and on march 16 you reuploaded all the 5 day schedule era videos you had made here up to that point over there. march 16 also is where YouTube is linked in the expert page.
sounds like you answered your own question, fully and accurately
