From what I've read about all the super spreading events, none of them involve surfaces exclusively. Some, like the office events, could have had surface involvement. The rest were aerosol and droplets in the air.

Without a comparative test for aerosols or airborne droplets, your surface test can't be compared to those. Nor did your test measure the dose, it appears to be been entirely qualitative.

Congratulations, you have a gift when it comes to stringing together fancy technical jargon, to say something that contradicts years of hazmat training, common sense, and nearly every expert on the subject. They especially need more people like you in the marijuana industry to continue to assure people that it is completely harmless and in fact it is beneficial to puppies, kittens and small children especially. /s

Just pulling your chain... it would be difficult to quantify which method of transmission would result in the greatest viral load. But keeping your hands clean and not touching your face when they are contaminated is a commonly accepted part of preventing the spread of disease. If you want to argue that in this situation that it is not important, because of what you have read about the "super spreading events", it probably isn't going to win you a prize in the Virologist of the Year competition, but who knows?
