I don’t know how valuable it is to compare to FR24 or any other site. They’re not the ones feeding the sim with injected data. So what they have is what likely will appear in the sim, understanding that the sim, for performance reasons, will only show aircraft within a roughly 70 to 80 NM diameter around the player’s aircraft. Anything outside of that is despawned/destroyed, and revived only if their PIM (path of intended movement) intersects the player’s “bubble” later on. This has been the case for a few SU versions now.
70-80NM btw, is about 20 AI aircraft typically. That’s actually quite busy.
