I didn't check my frame until after I took the starter (using the Find Seed by IVs feature of RNG Reporter). I basically just found out which frame the NPCs like to advance to, and then abused my ID/SID for a seed with that target frame. So like, I hit my delay, took the starter ASAP, checked its IVs to see what frame I hit. The NPCs almost always advanced to frame 6, so I abused my ID/SID for a spread with a Method 1 target frame of 6 and I got my Piplup! :)
