Also, as someone who hasn't cleared 5-4 yet, you actually have an advantage, as you can exploit final form farming (I wouldn't advise it though, as you will lose non-subs exp. and will need more time to cover 5-5 points).

For 5-3, you can use 4+ subs, with 10-20% clear rate you will need 20-40 sorties (if you bucket, this is few hours).
