maybe a native speaker can teach me what does he really mean by the word "relatively"? like
“We’re seeing relatively professional flying"
"we’re relatively impressed with the command and control associated with the J-20.”
This word is in the context of the many other "unprofessional" flying intercepts that have occurred between US aircraft and Chinese aircraft in the past where one or both decide to get a little too close. Or with Russia aircraft performing intercepts that get "too close".
Of course they have a point but they're also flying bombers, sigint, and other aircraft very close to Chinese borders. While not in Chinese airspace, well within sigint range and whenever one goes up to collect data and spy, all nearby platforms need to respond by not acting normally or as they would lol and certainly switching many things off. The Americans know this because they are stronger and so they do the aggression. China at the moment can't exactly do the same to the US because it should not initiate or pick a military confrontation whereas the US sees fit to fly bombers, fighters, and spy planes right next to your border since they are strong. China does it to Taiwan and Taiwan in the past did it to mainland when Taiwan was militarily stronger. Now Taiwan does no such thing because it potentially initiates war when they are on the weaker footing. China Taiwan issue though is one of civil war, the US is doing such things to others out of expressing its hegemonic status.
We've long since conjectured that J-20 has retractable luneberg lens and basically that's confirmed. It is highly dubious that F-35 and J-20 are out there in full stealth mode in the same vicinity and in the vicinity of various sigint and airborne aewc/awacs. We've got confirmation from Chinese side they are flying J-20s around the Pacific and confirmation from the Americans too.
