There is currently no open source info on that.
We know 3 years ago that a USAF pilot mentioned MKI pilots do 300 hours a year compared to their own 250 hours.
Overall, our flying hours won't be that great for other platforms because all of them are old. PLAAF is in the same boat. But they source parts from their own industry which makes it better. But we have no idea how many hours their pilots fly.
PAF has obtained new planes with regard to F-7PG, JF-17 and F-16 in the last decade. So, their flying hours would be a little higher. They have a 100 new planes and 250 old planes compared to 150-170 new planes and 550 old planes(80 Mig-21s are grounded) for IAF. That gives a new: old ratio of 1:2.5 for PAF and 1:3.5 for IAF.
