At correction factor two, the sampled model does not damp. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
The boundary correction bounces without damping
Correction factor 2 gives states 0, 16, 0, 16 volts.
0,16,0,16
The boundary is not labeled stable
The strict margin gate requires correction less than 2, so correction 2 fails.
