Here is my observation (just my humble opinion):
I think Patrick's jump is indeed not that consistent, not like Yuna or the skater you mentioned above (who seems like a machine). Yuna always do full run-throughs and have more than 90% successful rate in all her practice. However, she still only cleaned twice back to back in all her competitions. Patrick's jump technique is very difficult to be clean. because, he throws himself into his jumps, his jump is powerful with huge speed (similar to Han's), when landed is really marvelous. Such as his 4T-3T. However, his jump is not as effortless as Yuzuru's or Yuna's. because of this feature of his jumping technique, he need extreme precision in his jumping entry pattern/pacing/timing for him to land perfectly, which is completely different from Plushy, who can stick his landing, even tilted in the air. what'smore, Patrick's program is indeed intricate and full of transitions, timed to music, which make it even more difficult for consistency.
Therefore, a tiny bit of disturbance in mind (such as nerve, think too much etc.) will mess up a lot, Like he said, he should trust his rhythm/music/breathe, should not think too much, like his 3A, he clearly overdone it. When Jeremy went into his 4T, he thought too much and fell hard, then he let it all go just trusted his body, he landed everything else. Yuzuru usually falls on his opening 4S, because he also thinks too much, however, during the second half of his program, when he is a bit tired, he just reply on his body, he lands more jumps. You either let it all go, or practice and practice until 100% confident.
The loss of Gold medal must be extremely devastating for Patrick, so many what-if's, so many regrets. if he retires after this, I totally understand, and wish him best of luck, I will never forget his SP at 2013 worlds, which I have the privilege to watch it live (the most impressive ever skating performance in my short skating viewing life about 2 years, after that performance, I never cared about all the trash talk about Chan-flation whatsoever). He have done a lot for Canada, because of him Canada is the force in men's skating in the last quad (can you imagine without Patrick, what will Canada do...).
If he still find passion and love about figure skating and wanna compete again, no matter it is year by year, or take a break and come back for the next Oly. I wish he can have a peace of mind. continue pushing the boundaries artistically and technically (just like he did in the past quad). perform for his audience and for the fun/love of performance. If he wants to compete. he need to make a strategic plan and fix his problems(really face his weakness and fix it, if necessary even learn from your rivals), his jumping consistency (stick his landing, his 3A). and be really confident about his jumps and performance, not just pretend to be confident for his country/fans (which unfortunately transformed as arrogance at times).
Figure skating is a harsh sport, with the way Patrick skates (powerful with full speed and grandiose),it is a miracle that he did not have major injuries so far, Patrick has passed his prime. I dont wanna him come back for the superficial OGM glory and suffer injuries like Plushy. (If Patrick cannot do 2 quads anymore due to physical limitation, no big deal, as long as Patrick enjoyed his skating and performance for the audience).This OG is just one competition, a bad and disappointing one, learn from it, and move on. really no big deal. If Patrick put on a good performance, I will be really proud for him, personally, I dont care about OGM. But I was also disappointed, Patrick did not perform a great four seasons (the most complete/magnificent man's program of this season).
But, I will only thank him for all his effort during all these years. So many young skaters, Han, Yuzuru, Michael Christian Martinez,... worship Patrick and learn from him...
I wish skating will leave a positive memory for Patrick (not haunting him forever because of loss of OGM), if he decided to continue to be involved in figure skating and build a rink etc. That would be

Patrick, dont be too sad, I love your skating. You are a precious skater!
I feel sorry for Patrick, since so many negativity around him. I think people really should appreciate Patrick more...
