how often do these videos come out? everyday? every 2 days?
Depends on the series.
Blonaco (a track I'm building in Blockland that I decided to make a video series out of): Comes out on the first Saturday of every month and the third Saturday of every month.
Speed Draw (more like rendering): Comes out on the second Sunday and fourth Sunday of every month.
Track Attack (a series where I do hot laps on the mobile racing game Assoluto Racing): Comes out on the first Tuesday and the third Thursday of every month beginning from February of 2018.
I think it's safe to say that each series alternate with each other. So give or take I've got videos coming out every week (mostly on the weekends). To think of it another way:
Blonaco goes by
odd numbers (the 1st and the 3rd of any given month).
Speed Draw goes by
even numbers (the 2nd and the 4th of any given month).
Track Attack goes by
odd numbers, except it gets published during the week.
