I assume that was meant to be cheeky humor, even though I didn't laugh. Personal scores are relevant regardless of who is in the building at the same time as another skater. Further, Ilia has a well-established international history of lackluster PCS in the 70's. And I'm being more than generous in choosing the word lackluster to describe it. Lucky him. It's Friday and I'm in a good mood.
Let's leave out Brown, if you like. My observation would still be: "What a crappy score for a program with 4 quads."
Have you ever considered the cause for your obsession with Hanyu from thread to thread? His falling twice at an event is no more relevant to this discussion than Patrick Chan's falling twice at an event. As for yet another "bad look" comment coming from you, try and find the root cause for that as well. It seems to be personal.
LOL nice to see you're in a good mood!

But
well-established history? Come on - be fair, Malinin has literally had 3 international senior competitions, and this is a hybrid junior-senior season for him at that and he hasn't even had a senior season. And lackluster PCS in the 70's? As mentioned, he's not even really a senior yet, and at the most recent junior Worlds, nobody got in the 80's on PCS, including a certain "lackluster" Yuma Kagiyama - who only started scoring in the 80s when he turned senior.
Also, just an FYI, there are other elements in a program other than those 4 jumping passes, and sometimes just because a skater lands X number of quads doesn't mean they'll score higher than if they performed with X-1 or X-2 quads executed. I'll illustrate this by continuing my obsession with Hanyu from thread to thread, and pointing out that he scored 187.37 at the 2016 GPF FS with 3 quads, 194.08 at the 2015 GPF FS with 2 quads, and 219.48 at the 2014 GPF FS with 3 quads. How was it possible for him to get 219.48 with 3 quads and 187.37 with 3 quads?! Well, look at the rest of the protocol, and the other elements. After that, under -5/+5 system... Hanyu landed 4 quads at WTT and got 200.49, and landed 4 quads at Worlds and got 223.20. At the 2019 GPF, Hanyu landed 5 quads and got 194.00 points - a month earlier at NHK with 4 landed quads he got 195.71.
Point being, you can't just look at the number of quads. Malinin had a UR fall on his quad lutz, and a q called on his 4T, which dropped the GOE. Had Malinin done everything else cleanly, then yeah, I might have wondered why a program with 4 quads scored "only" 176.14 points (which is more than seasoned veteran seniors' seasons best FS like Messing, Aymoz, Aliev), but of course I wouldn't just count the quads I would look at overall execution of all elements. 176.14 isn't chump change for someone who has never had an international GP. Had he landed the quad lutz cleanly, as he can, he would have one of the top 10 freeskate scores of the season. Also, let's be honest, if Malinin had scored PCS over 80, you'd then gripe that it was overscored (which of course I would surmise you will be doing when Malinin actually starts his first full senior season and getting PCS in the 80's), but when it's under 80 you muse that it's a lacklustre score because it's only in the 70's. FYI, half the senior guys at Worlds 2021 didn't clear 80 PCS.
