You can probably just do multiplication to find it out.

(TOTAL NP UP)*(TOTAL BUSTER UP)*(TOTAL ATTACK UP) = Total damage multiplier

[Other modifiers not being considered here]

Considering a NLB black grail then level 10 Mystic Codes, and using Illya as the servant at 100% overcharge and Buster UP skill giving 50% BUSTER UP, then 10/10/10 Single Merlin you have:

(1+0.6+0.5)*(1+0.2+0.5+0.5)*(1+0.2) => (2.1)*(2.2)*(1.2) = 5,544x for Fragments of 2004 Mystic Code

(1+0.6)*(1+0.2+0.5+0.5)*(1+0.2+0.5) => (1.6)*(2.2)*(1.7) = 5,984x for Default Mystic Code

In this case, you get some 10%~ damage more with the Default Mystic Code, if I didn't do something stupid in that math.
