The "geniuses" at the White House are trying to put a lipstick on this pig by posting this equation for the tariff supposedly charged by other countries, with impressive-looking Greek symbols.
As many have pointed out, the ϵ * φ factor is 1, since they chose ε = 4 and φ = 0.25; hence, the formula reduces to simply the trade deficit divided by imports, which has no relationship with the actual tariff rates charged by the country on U.S. goods.
