10k in 4 hits is correct in your example.

As for your question about how the damage increase works, it doesn't matter because you get the same result either way.

If the damage is increased after it's cut, then you get 10,000 / 2 = 5,000 x 30% = 6,500

If the damage is increased before it's cut, then you get 10,000 x 30% = 13,000 / 2 = 6,500

All you really need to know about Fifth form is that it increases Musashis star gen and NP gain by 100% and if you increase it's level, then it also increases your attack power.
