While the quantities were essentially correct (it took about 1,100 litres of urine to make about 60 g of phosphorus), it was unnecessary to allow the urine to rot first.
Kuigi kogused olid enam-vähem õiged (läks vaja 1,1 liitrit uriini, et toota 60 g fosforit), ei olnud vaja lasta uriinil roiskuma minna.
