Frankly it might be faster to sparkle Isuzu once at 1-1, then just spam 1-5 A. Less animation time (ASW animation takes forever), and unless Isuzu misses/scratches on the single sub there's nothing that can damage your other ships, so morale on non-Isuzu is a non-issue. Sadly not being in the flagship position means you do have to worry about morale loss, but she's still only losing 4 morale per sortie.

For the flagship, 1 S-rank + MVP node of 4-3 (1188xp) is equivalent to 4.4 S-rank non-MVP sorties of 1-5 A  (270xp each). If only the flagship, Isuzu Kai Ni, a Maruyu and another sub are used (4 ships needed to get access to Line Abreast while subs are there to minimize resource usage), and assuming a non-Mutsuki class DD is being leveled (I used Ayanami Kai), 1 run of 1-5 A only takes 12 fuel and 16 ammo; 4.4 runs would take 52.8 and 70.4 respectively. From my experience running 4-3 with a DD/BB/2xCLT/2xCV fleet, 2 nodes takes about 100 fuel and 150 ammo. Considering the chance to go to node J and repair costs in 4-3, spamming 1-5 A might just be marginally more resource efficient even for leveling just 1 ship. Not sure which is faster though; I haven't timed either map.
