Long bursts more effective than multiple short ones?

I don't remember ever having read anywhere the principle on which it is based the damage model of IL-2, and, when they lack the basic information, you can imagine anything.

I mean, it matters of "bubbles" like in EAW or damage boxes, and how are they dimensioned?

Then, each of them how many states of damage does have? And transition from a state of damage to next is a matter of "points" given by incoming bullets?

I think that without these info (and more) we can't answer to your question. In principle, two bullets on same spot should give the very same effect, independently from their separation in time.

BTW, about hypothesized effect of bullets on a stressed structure, there's no official evidence. From 4.10 Guide: "Once damaged then its structural integrity is reduced so the ultimate load reduces as well." That's to say bullet hits reduce available G-load, but this latter admittedly does not affect resistance to bullet.
