UR TOMH 探偵オペラ ミルキィホームズ Part 03 1st Chase and Solve plus Declaration, Return, Reunion & Chapter Arrangement Pick

Not really sure how the choice of who gets their 'PSP' 1st affects both the enemy chapter sequence or who gets priority when there is a tie on the trust points for the 4 girls, as on my 1st run playlist, the date I got was different from what I got in this new playlist, though I did the exact thing gaining the same amount of trust points for all 4. Maybe it's who I talk to first and/or last per chapter that determines the priority? Does who gets their device after meeting Kamitsu also affect? If anyone knows, please say so via a comment in this video.
