From the above;
The First Instance Court, commenting on the fact that the accused had made the first contact with the English service used by the victim before calling Filomena Romanelli, hypothesized that the telephone call made to the service of the victim had been done with the sole aim of checking that the cell phones, removed after the murder from the dwelling in Via della Pergola, had not been found by anyone. The comment is valid, since it does not otherwise make sense, even putting aside the timing of the telephone calls which the defendant changed in the course of the hearings, why Amanda Marie Knox, in the event she had had the intention of finding out about her English friend’s condition, not having received a reply from the English telephone service used by Meredith Kercher, did not try to call the other service, the one with an Italian SIM card, of which the accused was perfectly aware.
This is NOT a fact, nor was it proven by the court. It's an opinion, and it's not even a logical one. As has been pointed out, Amanda and Meredith, when talking on the phone, always used Meredith's English phone, not the Italian one. So why would Amanda think of using a phone the two of them never used?
Next, we have this;
From the telephone records it appears that the telephone call made at 12:11:02 pm to the Italian Vodafone service of the victim lasted 3 seconds; the one at 12:11:54 pm to the English service of the victim lasted 4 seconds. Perhaps not even enough time to repeat the first ring. Filomena Romanelli indeed made two unsuccessful calls to the service used by Amanda Marie Knox, at 12:12:35 pm and at 12:20:44 pm, and let the defendant’s telephone ring for 36 seconds the first time, and for a good 65 seconds the second time; an insistence that appears normal for anyone who intends to speak on the telephone with someone who, however, does not immediately answer the telephone.
Here the court is displaying it's utter lack of understanding on how phone systems work. Filomena didn't let the phone ring 36 seconds and later, 65 seconds. As has been noted numerous times, the duration of a call is only based on after the call is answered. In both cases above, Amanda answered the call and spoke to Filomena, and that's how the calls got to 36 and 65 seconds in duration.
And more;
The telephone is allowed to ring for a considerable period of time in the hope of receiving a reply before resigning oneself to ending the call. But that did not happen when Amanda Marie Knox called the two cell phones used by Meredith Kercher. These are two calls that barely registered.
More evidence the court doesn't understand how the phone network works. The two calls were short because (1) Amanda chose not to leave a VM when she started hearing the message and (2) because the phone was out of service and it only took a couple of seconds to understand that message.
And finally;
The fact that the two calls to services used by Meredith Kercher did not alarm the defendant has only one plausible explanation. There was no concern at all in the mind of Amanda Marie Knox when she hurried to make the two telephone calls to the young English woman simply because she knew very well that Meredith Kercher could not have answered the calls; calls which had to be made because Filomena Romanelli insisted, but which the defendant knew [154] were useless.
Here the court has decided, much like yourself, they can read the minds of others. It seems pretty clear to me that Amanda WAS very much concerned, yet the court, because it doesn't understand how the phone system works, has concluded two short calls to Meredith's two numbers is evidence Amanda wasn't concerned.
So, what you posted does establish some facts, such as when the calls were made. But it also clearly established the court didn't understand how phone networks work, and as a result of that ignorance, formed an opinion which has no merit. As for what was proven... other than the court was pretty ignorant on phone networks, it didn't prove a damn thing.
