So I'm assuming its not necessary to have tick-by-tick data in order to analyse the tape?
From what i've read, Interactive Brokers gives data approximately every 0.2 seconds. is this still ok?

Also how long did it take for you guys to become confident at it? Was there a moment where things just 'clicked'?

I've been watching the time and sales on a demo account and its still pretty confusing i must admit.!
