S26 Milk

Hello mommies, who's using an S26 milk for newborn? Confused kami ni hubby papano ititimpla sabi kasi sa babybook ni baby 1 oz of water = 1 scoop but sa box ng S26, 2 oz of water = 1 scoop. Any thoughts po? Or kung papaano niyo po tinitimpla? I texted our Pedia pero she's not responding pa. PLEASE HELP!!! :(
