So based on the sample given, the MAX is almost as dangerous as the first generation of transport jets and just one more hull loss would give it the record. Time in service needs to be looked at as well, the A320 and B777 have excellent records accumulated over 24 - 30 years which is long enough for a meaningful result. The MAX suffered two disasters from the same cause in under two years which gives a spike.
If the problems are sorted out and it returns to service with no further accidents then the rate would decrease overtime and could be better than average. Had it not been grounded and another accident occurred, that would have been the end.
This could be Boeing’s equivalent of de Havilland’s Comet, whilst the type eventually returned to service, sales never recovered and the company lost its premier position in the market. The British manufacturer wasn’t cranking out 40 - 50 aircraft a month during the grounding either.
