If you look at the ROCMOD information about ADIZ incursions, there are airframes like the H-6 that enters as well, which means there are airframes being pulled from other theater commands, most likely STC.
But let's take the assumption that all the aircrafts are coming from the ETC.
PLAAF operations from the 7th onward:
- 66 airframes on the 7th
- 39 airframes on the 8th
- 45 airframes on the 9th
- 36 airframes on the 10th
- 21 airframes on the 11th
- 24 airframes on the 12th
- 29 airframes on the 13th
- 22 airframes on the 14th
- 30 airframes on the 15th
- 17 airframes on the 16th
- 21 airframes on the 17th
- 51 airframes on the 18th
If the PLAAF is demonstrating that they can perform high intensity ops on a regular basis - i.e. land a jet, refuel, rearm, and relaunch, then they should be able to maintain 50 sorties per day. But they're not.
In fact, after the 9th, they had to reduce ops for 9 days until they can launch another 50+ airframes.
Sortie generation is hard, and most air forces are bad at it. We have little data from the ROC about their sortie generation capabilities and I do suspect that it's probably significantly lower just due to training and budgetary constraints, it's also worth remembering that the PLAAF is not 10 ft tall. They've made great strides in improving their capabilities but they're not there yet.

As a general message: it's not a bad thing to point out that there are still deficiencies. And there certainly
are deficiencies in the PLAAF.
Remember where they were as recently as 10 years ago. It would be ludicrous to assume that they've not only managed to fix all their institutional problems in the last 10 years (b/c institutional inertia is a thing) but outright surpassed the one country in the world that has been running high intensity ops for decades. That's the height of hubris.
If you know where you're deficient, you know where you can make improvements.
The worst thing anyone can do is to bury their head in the sand and claim that anything that points out PLA/AF/AN deficiencies is "westoid/Indian/wanwan fantasies" or some other brain dead nationalist chestbeating. Otherwise, how are you any different from the ROC claiming a civilian drone hovering over Kinmen is a "high altitude drone using telescope lens" or that "PLARF missiles flew too high for us to intercept"?
Arrogance and hubris loses wars. Honest self-criticism and seeking improvements wins them.
