Yep, the Poolmath calculator confirms close to 1.5 gallons to raise your FC from zero to 10-11, so stick with it. You have some serious organics and/or ammonia tearing-up that chlorine. At some point, your FC will begin to hold and start to hoover around 10 longer. Keep with the 10-min drill. Good luck.
