firstly we do not accept israeli statistics about interception rates. secondly they do not even claim that interception % against ballistic missiles. thirdly that was interception rate by USA + UK + France + Israel + Jordan. fourthly the objective was to strike the IAF base which launched the F-35s which attacked the Iranian consulate building, and that was clearly achieved as per video footage and satellite imagery.
Firstly, the Israelis and allies do not care if anyone believe the interception claims, or not.
Here is why...And I will simplify a bit...
1- Parking lot
2- Hospital
3- Electrical station
4- Army HQ
5- Bank building
Which is most important? 2- Hospital, of course.
Army HQ is more an administrative/bureaucracy structure than an actual war planning office.
Next important is 3- Electrical station.
If five missiles launched, each against the five targets listed, and only items 2 and 3 were intercepted, that would be %100 successful interception. Because items 1, 4, and 5 are tactically irrelevant. Go ahead and destroy them. The post war records will show that the hospital and the power station were successfully defended despite repeated attacks, and that is what matters in terms of technical aspects and combat tactics.
So, drawing from Desert Storm experience, air defense for the hospital is more from accident than from deliberate attack, whereas, the power station would be the deliberate attack. We would deploy air defense for the hospital for humanitarian reason, whereas, air defense for the power station is for genuine combat tactics. Would Iran launch a missile against an Israeli hospital? We do not know and basically, we do not care. The hospital must be defended anyway, if at least from an errant missile intended for somewhere else. In the end, as long as the hospital was successfully defended, the defense method was a success.
Criticize Israeli sources all you want, but you would be missing the point.
