Having read a fair amount of info on this thread and others, I think I have understood some of the basics.

I am trying to book a C1-C3-C1 RT and have identified a 3x in C3, which drops half the YQ / YR. I have played around a bit on ITA but have not been able to dump all the YQ / YR. Is there a standardized set of next steps that I should be exploring that may work to dump the remaining YQ / YR?

Thanks for your pointers in advance.
