The area where the rock landed if it were thrown from outside is a little weird. I cannot think of any scenario where a rock that size flies through a glass window, damages the shutter to the extend it has. Only to have it bounce at a rather odd angle with all forward momentum gone to the ground but yet have enough force to knock over both the shoulder bag and paper bag.
Also, there appears to some rock slivers below the torn paper bag. If that's the case, it would also tell us that something strange is going on since the bulk of the stone is on top of the paper bag. How did those slivers end up there.
.
Beyond your observations, Amazer, there are further incongruencies with the defence's official explanation of the rock throwing.
Here are some overlayed photograms from the Sollecito rock expert. You see how the rock is thrown, and in fact in photogram 4 you see the hands which have come up to give the rock its desired launch and parabola.

The next image (below) which is not from the case, shows the posture and followthrough required to launch the rock as per the Sollecito tests.
Now the problem is that there is no ground, only empty space in front of Filomena's window. If the person who throughs the rock does so from the car parking platform, there's a fence in the way. Of course, the thrower could scramble over the fence, be perched on the threshold of they abyss, hang on to the fence with one hand behind his back, and do the underhand bowling through with the other, but that's really asking too much, especially when this scene would be in full, illuminated view of the neighbours and passers-by:
Another option is that the Sollecito-Knox fantasy intruder throw the rock shot-put style, but that would give it different flight characteristics from the defence expert test. As well, I would think that it would be imprecise, and there are no marks on the outer wall from "missed" rock launchings, nor rocks accumulated below from these missed attempts.
So, assuming somethow the window's glass pane was broken, now the intruder climbs up. To do so he has to run all the way around the house, to get to the lower level. The iron grating of the lower boys' floor window only allowed a Sollecito team lawyer to get to touch the window sill at the bottom of Filomena's window.
His feet are perched uncomfortably on the iron grate. Only one of his feet is taking weight (the other , his left foot, is jammed in a narrow space, twisted at an angle)
His hands touch the window sill, which sticks out a centimetre or two. Since the window sill sheds water from the window area, it is at a slightly downward sloping angle. The only real grip on the sill is a pinching grip, thumb below and index finger on top. There is no real friction gripping for the feet on the vertical wall. Maybe an expert rock climber could go higher.
There are not many "drifters" who are "drug dealers" (FOA and Knox Entourage descriptions of Rudy) who could do that. I rock climbed in a former life, and I would not be able to haul myself up to the window.
How to get through the window is the next question:
There's much more, but just with this fast glance at the problems associated with breaking in to the cottage from Fiomena's window, we should be able to put the issue to rest, especially when we know that the express lane access for burglars into the cottage is through the discrete privacy of the balcony on the other side of the house, which Rudy was familiar with.
