@mrchan @Comparativist The industry study ignored things like sitting on the ground, boarding/unboarding, risk at airport, taking off masks to eat/drink (or not wearing properly, or inferior to the surgical masks they assumed), and they still came up with 2% per hour (pre-alpha variant).
@Chan女士@Comparativist该行业研究忽略了诸如坐在地上、登机/退票、在机场冒险、摘下口罩吃/喝（或未正确佩戴，或低于他们假设的外科口罩）之类的事情，他们仍然得出了每小时2%的分数（阿尔法前变体）。
