Yup I meant to develop in Dektol 1:9, and instead I carefully measured 1 part Dektol. Asked my wife what's 9 times 3. She told me 27 and I carelessly rinsed out the beaker, added 9 parts water and saw it was short of the 30 ounces total, so I added 3 more ounces of water.
I developed a roll of film for 5 minutes in 10 parts water last night.
