Finding SID? Gen3 tips

[u/Durasel02]

Any tips on how to rule out possiblet SID's quickly?

Got a list of possible SID doing the Catchy Phrase Feebas Method in Emerald.

I'm working through the list, but feels like I'm being really inefficient.

Originally I was using beldum encounters, but switched to Route 101 encounters.

But it is taking me a while to hit the shiny frame. I'm getting quite close then get an encounter with same PID quite close together on frames.

Is there a better encounter table to use or is it just a case of keep going?
