Before 2.0 Soylent was sold at the smallest level (one pouch) = one day. After that the next smallest was one week (seven pouches). And everything after that was a unit of weeks.
Now with 2.0 it is sold in 12 packs of 400cal. which if you are consuming 2000cal / day only lasts for 3 days.
For 7 days you would need 28 bottles, but there is no option to buy 28 bottles. You would have to choose between 24 or 36.
For one month you would want 112 bottles, the closest you can get is 108 or 120
Why did they decide to go with 12 rather than something like 28 bottles = one week?
