For Fun! For GLORY!!
RTA = Real Time Attack. In short it means you start timing when you gain control of your character, and stop timing when you lose control. So from when Scrooge appears on the money bin to when he lands on the last platform of the escape. It doesn't really matter what you use to record, but I use WSplit so I can keep track of how good/bad each level is compared to my PB. It also shows up on my stream so...yeah.
