If you have good F 2 L and know 2 look OLL and 2 look PLL sub 20 is possible . But I ' m guessing when you get closer to 30 seconds learning full PLL will seem less daunting and you ' ll learn it . <| sep |> And no longer have billions invested into parts of our country that our own govt doest care about . Well fucking done <| sep |> I ' ve done research studies involving an MRI before . Was told I had to try and stay awake for accuracy . That was pretty much the hardest task I ' ve faced . I ' m pretty sure I drifted off a couple of times . That or I started hallucinating . It was just over an hour total , but the longest section of scans was only 17 minutes . Even the 56 minute ones I had to fight to stay awake . I dunno what it is about them , but they completely send me off .
