The placement change column is the ranking by Sinclair - USAW ranking system. It shows how a lifter increases or drops in ranking, simply by switching to the "3rd place average method".
The most dramatic changes are a drop in ranking by 5 places. As our National teams have a maximum of 7 spots per team, in non-technical terms, 5 places is a pretty big deal.
Note, there is one lifter who shows-up in our top 20 rankings (#13) and is not even top 23 in the Sinclair rankings. Likewise, one of the top 20 lifters on Sinclair does not show-up in the Top 20 official ranking.
I am not advocating that only the Sinclair formula is used to pick teams. I am asserting that it IS used by other countries, who are winning more medals than us, to help select teams, hence our ranking system should have some agreement with it.
