Flight frequency is still less than half of normal. With reduced frequency you wouldn't expect a years worth of total engine failures in a week.
Poisson distribution could tell how improbable it is but I'm lazy.

Weekly occurence of 0 has 13.5% chance of happening this being the case for 7 weeks before this last 8th 2021, 13.5*7/8= 11.8% so far.
But I'm no statistician.

At a weekly probability of 0.04 (2 failures/52 weeks) the probability of 2 failures within a week is 0.077%. The probability of 0 failures in a week is 96%.
Accounting or halving of flight frequency it's 0.02% and 98% respectively.
