I don't think the Germans use the Kruegers on the IDS anymore (unless things have changed) and they are not fitted to the ECR variant either. I think Italy is the only nation with operable Kruegers now, but I am a bit out of the loop.
I think 7 kts was claimed but our FRCs only gave a 4 kts reduction (my brain cells are probably in a worse state than yours though).
