Menus, shops and equipment selection can all be significantly improved. I had a couple of routing runs before doing this so I dare say I might have another crack at this.
A lot of the big stuff did go pretty well though, of course the omni level chad Ogre in phase 4 cost a lot of time. That is a new record for the amount of damage I have seen on of those things take.
If anyone is curious about the MN route, it is almost identical to Normal as due to equipment you are just going to be using Inazuma to delete most waves and with the damage boost of GOM and Azure helm the bosses aren't that much different.
The biggest time loss vs. NGB is the just the performance in Sigma. Load times are longer and the menus are a lot more sluggish, both items and Murumasa.
Still this is a pretty good blueprint and the run is super fun as you're just blasing through everything. Turns out the MC firewheels ticks Ishtaros too much for combos to connect so you're best off with the usual tactic.
I ran against some old splits I had from NGB EL because I was too lazy to create new ones. They don't really line up as well and I forgot to split in a few spots.
Oh and one last thing I didn't get the fish at the end of phase 4 which is huge. That costs you around 30 seconds and is a total coin flip unfortunately.
mod note: Start split was 1s late
