Okay, I'm familiar with measuring temperature by the eyes and I get your point (which essentially seems to be the same as traditional guidance i.e. don't steep the tea in boiling water. You're just accounting for the variance in temperature from boiling and pouring) but I'm not sure I follow how this means merchants are trying to sell you bad tea.
Plus there doesn't account for other green teas that aren't poured in accordance with Chinese tea ceremony, such as the Nepalese green I had earlier today.
