It is pretty obvious the Ukrainians have issues even properly tracking those missiles. On the day the Russians fired two Kinzhal missiles the Ukrainians claimed to have shot down six of them. They are basically tracking decoys.That was the day Russia launched 11 iskanders and all were intercepted. Believe it or not missile on missile hit does not disintegrate both objects big huge chunks survive and rain down.
There is also plenty of evidence of PAC-3 interceptors crashing pretty much intact several times. So the concept all missiles launched lead to interceptions is clear evident BS.
The Ukrainian government has a clear track record of claiming more interceptions than missiles fired by the opposing side. And then there are the magic Russian missiles which seem to be able to hit more than one target. Since the Russians consistently hit more targets than amount of non-intercepted Russian missiles claimed by Ukraine.
