I agree, aggregates are better to look at than records, records being anomalies as stated above.
Having said that, something to consider about the records listed in the link above is that (I'm 99% sure) the numbers are normalized to 100 yards. In other words, the records are reported in MOA not absolute inches. That's why you can have a single number represent an average for multiple ranges.
Example: Walt Berger, 5 10-shot groups at 100, 200 & 300, record is 0.3555. Not inches, but normalized to 100 yards.
I've seen BR match results reported this way, and I'm almost certain that's how these records are reported.
So, looking at it that way, the records are indicating (in almost every case) that the longer distance groups are proportionally larger than closer range groups.
