Because what you said was basically "Very few used it but it is still a big part of the history of the plane."
I did not say "very few used it"
The only mention of the word few was "With the 410
A, only a few planes carried the 103"
Later I said that I personally estimate the number of Mk 103 equipped planes in the rage of about 200. (out of ~1200)
That's not all, that's not "most", but still a big part of the 410's history.
