On a balanced split, roughly 10 misses in Reading and Writing and 9 in Math, which is 700 per section. Any total from 1400 upward requires reaching the harder Module 2 in both sections, because the easier path carries a scaled ceiling in the low 1300s.
Nineteen misses is the most forgiving of the common targets, but the routing requirement is identical to 1600's: the harder Module 2 in both sections. That is the counterintuitive part of digital SAT scoring, and it means Module 1 accuracy matters just as much at 1400 as at the top of the scale.
