You have any Stats / data to demonstate that statement ? Because we don't , We have data that demonstrate that the drastic redictions in mid-airs is due to Short term conflic alerts being introduced widely in ATC . To us TCAS caused f more loss of separation ( I said separation, not collision risks) than saving the day. .
To close the discussion on the ACAS u/s 72 hours grace or MEL conditions , remember TCAS is ony mandatory for large aircraft , and even then excluding State aircraft and military, There are far , far more flying "things" flying around which are not equipped , not even with transponders ( e.g gliders) which are plenty in class E airpace.on a good day. As I said before , TCAS is a nice piece of equipment adding one safety layer when working, , but even when working is no garantee at all you will not hit anybody else. So no problem for us if it is not working for 3 days on a single aircraft.
