I believe Supanut131 meant overall training. 4-3 will train the DD and CL flag while the support carriers and BB will gain decent exp. 5-4 is also good for overall training and I use normally if I'm not looking to powerlevel anything.

@OP

I believe the 3-2A method can train Hiryuu to kai ni in 1 day given that:

1) Carriers are gauranteed MVP with 3 torpedo palnes and 1 red with all the other carriers loaded with red

2) You can run 3-2-A with 1 morale lose per run, meaning that you can run 3-2-A 20 or more runs continuously before taking a 21 minute break and repeat. With each run taking 3-4 minutes max (Shouldn't go into the second shelling phrase), 1 cycle (20 runs with the break) should take 1.5hours and give 23040 exp per cycle, or 15350 exp per hour. So theorically it's possible to kai ni Hiryuu from lvl 1 in a single day with no break (From the exp page you'll need 343,000 exp, so that will take 22.36 hours)
