Slide two invented records

Compare a raw product sum with sign-only values. Predict the outlier’s effect before switching it on.

Shift B in sample intervals Add an oversized outlier to B Use only the sign (−1, 0, +1)

A index	A	Overlapping B	Product

The sum is divided by the number of overlapping pairs. It is not a Pearson correlation coefficient.

Deterministic toy sequences, not seismic data. Edge overlap changes with shift. Sign normalization removes amplitude information and does not preserve every signal property.
