It's easy to get caught up amid all this quad frenzy, after all figure skating is being revolutionized right before our eyes. On the one hand this is obviously great to see for this sport in general. However, we should also remember that these skaters are human beings with limitations to what their bodies can endure physically, and Javi is one of the oldest among them. The likes of Chen, Jin and Uno are several years younger, their bodies more flexible and adaptable, and have also undergone a much different method of training than Javi had when quads were more of a rarity and did not yet completely overwhelm the men's field.
I think Javi has maxed out on what's realistically possible for him to deliver in terms of jump content. Yes, he can do a 4Lo, but at this point in his career it's likely too late for him to try to master the jump in competition. Javi seems to know and understand this. Adding another 4T to his FS layout just to have 4 quads makes no sense, because the BV points he would gain from it would be lost having to drop the 2nd 3A because of the Zayak rules.
What Javi needs to focus on going forward is maximizing his GOE, and there's room for improvement. His quads are already getting consistently great GOE, and deservedly so, as he has some of the best 4T and 4S out of anyone. His 3A can use some work, adding some more difficult and/or varied transitions in and out of the jumps, increasing height, securing the landings even more, and this most recent video seems to be exactly a testament to that. He could work on his 3F too, which can sometimes get an unclear edge call and consequently lower the GOE of his big moneymaking 3F+1Lo+3S combo. There are actually a lot of points to gain just from these alone. Not to mention his spins, which also typically get a mix of +1 and +2, sometimes not even that.
His road to an Olympic medal is by skating two squeaky clean programs with his current layout. Let's not forget: his programs are still extremely difficult; he has a PCS advantage over the youngsters which would take much more than a season for them to catch up on, plus he does already have a GOE advantage too. If this is a "conservative" strategy and means he can medal but not reach gold, I would say so be it, after all he doesn't have a medal of any color yet. But if the incredible risks some of these guys are taking with all these new quads lead to a couple of messy landings or downright flawed skates under Olympic pressure and Javi will be the one staying on his feet, it may prove to be the winning strategy.
