The EDC17CV41 has been in the field for a long time on agricultural and commercial vehicles. That long life gives the library a concrete advantage: many different calibrations of the same ECU have built up.

What a wider donor pool changes
A patch depends on the calibration of the donor it was learned from. If the customer file has a different calibration, segments may not sit where they are expected. The more donors in the pool, the higher the chance of finding a calibration close to the incoming file.
In practice this means that on a mature platform like the EDC17CV41, "a solution exists but does not fit your file" happens less often than on new platforms. The system ranks candidate donors by fit and uses the candidate whose segments FULLY verify, not simply the first one that fits.
Same family, different size
CV41 and CV52 are members of the same family. The library can also match files of different sizes from the same family — but only when all segments verify. A size difference alone does not block matching; verification does.
