I don't think you will have to worry about sq1.... I averaged like 18 in my prime and I'm probably barely sub 20 nowdays. The scrambles all just ended up having EP cases I'm really familiar with which helped a lot
Should be 25 for OcR + 19 for NR single + 5 for winning the comp
So 49 (not many people have competed in SQ-1 in NZ or Aus)
Also this is really easy to find out so you should look it up on the WCA website
