the claimed numbers and paths shows that they actually have no idea how many PLAAF planes are in the air or their real paths.A large show of force from the Chinese side in reaction to Tsai's US tour, but I don't think it is sufficient to deter Taiwan. In fact this current reaction is more muted then when Pelosi visited Taiwan. China should consider economic sanctions as further steps.
the Taiwan strait is only 160 km across, 71 planes with standard spacing spans the strait 2 times, even with compressed 1 km spacing would span half the strait. They also wouldn't be able to make such tight turns even in the open, much less in highly constrained airspace like that.
