Just some food for thought, based on what happened over the past two years -- everyone was waiting for WL movement after CTE dates came and went. It never happens.
When you think about it, it makes perfect sense. 4/30 provokes big WL movement because it forces people to drop excess As. The ensuing calls from WLs all over the country cause secondary WL waves, as they create new people with multiple As, who then to drop the excess.
This continues until all vacancies are ultimately filled with people who did not previously hold an A. After that, you get scattered people dropping out for a variety of reasons, which cause a trickle of WL movement, but nothing big.
Then, CTE dates roll around. These cause people to drop off WLs all over the country, but do not result in multiple As being dropped. That already happened weeks before. PTE turning into CTE does not create vacancies that need to be filled. As a result, WLs certainly shrink as people withdraw from them, but no one is called off a WL because a PTE became a CTE.
