Having this number of incidents within a short period of time, is nothing more than chance. They are, almost certainly, unrelated but cause speculation due to the timeframe.
If there were one prang per month for the year, that would produce less speculation than 12 prangs in one month and then nothing for the rest of the year.
Until a calendar year has elapsed and the total figures of hulls and people lost can be compared with previous years - NOTHING can be surmised from the number of incidents.
Also, having several incidents in a short time is good for safety as it sharpens up all folks involved - including pax. That might be unpalatable but it is true.
