My runs are always 2x Sector 1 1x Sector 2 and 1x Sector 3 with pugs. I didn't even know you could run Sector 2 twice.
I have gotten 3 15*s out of the EQ so far ( Only 1 being from Sector 3 ). RNG is RNG, you could probably get the most runs and get nothing or get only 1 run of each sector and walk out with a 15* per run.
