While technically correct, this analysis is flawed. The amount your average moves depends on where it is otherwise.
The 14 points added to your QA from a single match was under the assumption that your average was low otherwise (40). However, the average will move less the higher up in QA you go.
Crunching the numbers, the QA shift is still significant while there is a radically different on the table, but I just wanted to clarify that 14 points is not always 14 points.That isn't to say the phenomenon doesn't exist.

In fact, looking at GTRE, if you remove the highest scoring Qualifier (which had the top 2 OPR on the same team), then 1246 would drop from rank 6 to around 36 - assuming they kept their average for their other matches.
However, this is also a function of the low point-scoring of a majority of teams there - "low point-scoring" to me is averages less than coopertition + a few noodles. This leads to many teams being near the same QA, thus you get rank jumping.
