What would happen if you completely disregarded the break in period? Am I good if I drive very strict from 340 miles till 1200 miles? Or has the damage been done if any?
I wouldn't worry about it as long as your engine wasn't cold. Just don't do it repeatedly/often.

The real key, and this can't really be fudged, is at the very least abide by the warning track on the tachometer. Better yet allow the engine to come up to operating temperature (based on the oil temperature) before starting any shenanigans.
