Together with the picture of the other side of the cockpit, which shows two intact windows on the FO side, and also no or few holes, it suggests that the impact of the high velocity objects are very local, conenctrated in a band running straight over the captain seat roughly in direction of door R1, fanning out.
Like a cone from a missile exploding to the left front of the aircraft.
Buk's warhead has 6000 or more striking elements. The very local impact means that almost all that charge was absorbed by the cockpit. However the deck's floor has a small number of holes.
