Without looking at the specific changes made, it is impossible to know whether this represents a real capability improvement. For example, maybe the 20% gain was due to a very obvious/easy to catch inefficiency while the 1% improvement was due to something subtle.

I'm not convinced. Both are improvements on something implemented by highly trained/credentialed/successful teams. Something "missed" by either team is impressive either way.
