Has anyone converted the Barry Thornton two bath higher definition formula to tablespoons or teaspoons? I don't have a gram scale and would prefer not to buy one if it's doable with standard measurements. Most of the scales on Amazon are only accurate to one gram, meaning that the 6.25 grams of metol may just be a ballpark anyway. If in your opinion these amounts are hypercritical and cannot be estimated through teaspoons, etc., please let me know. Also, I assume that for Bath A, you mix the metol in first, and then add the sodium sulphite. Is that correct?
