+## Summary: per-encoder means, marginalised over decoders
+
+Every encoder encoded the same 2000 rows and every decoder decoded every encoder's encodings, so each encoder's row is an average over the same decoders and source texts. Values are the decoder-balanced means (mean of the per-decoder means); `Rows` counts the kept rows behind each.
+For reference, the human source texts score 0.0616 (std 0.0942) on the same EditLens model.
