The linked handout shows the correct dosage by body weight: (see page 2 of the handout (little arrows top left) Each ~6 gm tube contains 6gm*1.78% = 113mg. Each tube has 25 notches so each notch equal 113mg/25 = 4.5mg. Example: 200lb man, from handout the dose is 18mg. 18mg/(4.5mg/notch) = 4 notches per dose. Or as some other posts have noted: 1 notch per 50lbs body weight. https://covid19criticalcare.com/covid-19-protocols/i-mask-plus-protocol/
