Click Pandora's Box, it's on the far right side of RNG Reporter. Then, in the left column, put the desired PID in. Set the delay, from 5500 to 6000 is reachable. Click Generate, and it will give you a list of IDs/SIDs that will make that spread shiny. Each ID/SID will also have a seed. Pick one combination and put the seed into the Seed (Hex) box. Click Seed to Time. RNG as usual.
1. How do I know what PID I want?
2. How do I know if I've hit my right delay upon starting the game?
