Column comparison

Your current column and the selected column, shown together.

76%Weighted similarity

4 of 8 scoring criteria are comparable, covering 59% of the total weight. Missing values are excluded.

The percentage includes partial similarity. Green means the recorded values match; red means they differ. The calculation below explains each contribution.

Similarity does not guarantee identical selectivity or performance. Confirm suitability for your method.

How this similarity score is calculated

Each comparable criterion earns its weight multiplied by its similarity. The sum is divided by the available weight, then multiplied by 100 and rounded. Missing criteria earn no points and add no weight. Vendor, Brand, Mode, length, internal diameter, pressure and temperature do not contribute to this percentage. Mode and Modification determine which families appear in recommendations.
