You can’t be sure how relevant and accurate the findings are, because we are not given all they considered and factored in. Was the time lost with the COVID lockdown factored, pilots who did get sick, and lost time flying. Did those who got sick have long COVID symptoms, and if so, were they ones that affected flying? Like “brain fog” and fatigue? And if none of that factored in, what about job loss or furloughed, and inflation that caused some not to fly as often, or delay dual instruction? So, there is much unknown here.
