Well, supposedly, Yukari organized the
Miharu's ammo storage so that they'd end up with a third of each in the rollbar launcher, meaning 8 of each. So, the actual content shown on the wiki would've been juggled around to...
Cargo bays
12 chibi-MEGAMI probes
8 AS-7 Anti-Matter torpedoes
24 AS-5a torpedoes
In rollbar launcher
5x AS-7-1-TA, Type 1 Transphasic Aether
8x AS-7-1-AM, Type 1 Anti-Matter
6x AS-7-1-SDM, Type 1 Subspace Detonator
Then some more were made. 3 more AS-7 transphasic aether and 2 more subspace detonator warheads.
So, the inventory before the fight started should've been:
In rollbar launcher
8x AS-7-1-TA, Type 1 Transphasic Aether
8x AS-7-1-AM, Type 1 Anti-Matter
8x AS-7-1-SDM, Type 1 Subspace Detonator
Miharu's torpedo usage so far...
2 TA ~ opening volley to destroy shuttles
2 AM ~ once emerging from Bowhordia's atmosphere to attack Obakemono
1 SDM ~ knocking out enemy shields to have the Black Knights teleport in the Yui destroyers and finish off Obakemono with main cannon
2 TA ~ to finish off Lamia armors
2 AM ~ to destroy Ketsueki corvette Nu 3
Following this, you can edit Miyoko's report in regard to the current inventory:
In rollbar launcher
4x AS-7-1-TA, Type 1 Transphasic Aether
4x AS-7-1-AM, Type 1 Anti-Matter
7x AS-7-1-SDM, Type 1 Subspace Detonator
Stored torpedoes in the cargo bays is uncertain, seeing the hull breach Miharu took where the Uriko bomber was normally stored. A damage report should confirm wether there were any losses or not )Yukari's in charge of asking for that).
I hope that helps.
