PSO2 NGS: I can't beat this time for some reason

(Music I was listening to in the background is from ULTRAKILL, The Cybergrind level, track is by MegaNeko I think.)
0m46s is just... The number I keep landing on for this.
I first got that record with pretty bad units, after a very lucky run where the Bujin didn't dodge any of my attacks, I got loads of crits, and got lucky with him proccing Photon Avenger at the very start on the third hit of Calibur Streak.

Now I have fully augmented geant units. Went from 36% melee potency to about 44.2%. Now I can consistently hit 0m46s, but I can't beat it.

Unit and weapon augments (the same for all 3 unit slots):
Units: Gigas Might II, Forms Soul II, Meltech Duable III, Might III
Weapon: Cattleya Sword, Mustered Might potential level 4, same augs as above, Fixa attack level 3
Battlepower: 1475
Attack: 928
