The last Friday in February? 
Will this push back Financial aid info? Into mid to late March?
UF wants to be a top 5 school, so how do those schools handle it?
UNC-CH
Early Action: Apply by October 15 to get your decision by the end of January.
Regular Decision: Apply by January 15 to get your decision by the end of March.
UVa:
Early-action decisions typically come out in January and regular application decisions will be released by the end of March
UM-Ann Arbor
Early Action by Nov. 1, and get initial notification – by Dec. 24.
Regular Decision by Feb. 1 – with students receiving decisions by early April.
UC Berkeley
A batch of early decisions was released on February 8; all regular decisions will become available at MAP@Berkeley on March 28, 2019
UCLA
All decisions became available at myApplication Status on March 22, 2019
Each UC campus will release the admission decisions on its own online system and on different dates throughout March (some UCs may release small batches of decisions earlier than March).
Lets add GT:
Early Action: App Deadline October 15 Decision Date January 12, 2019
Regular Decision: App Deadline January 1, Decision Day March 9, 2019
The UC’s are later than UF (March), while the others offer Early Action and Regular Decision (RD being later than UF).
What do those schools, that offer Early Action, all have in common? They depend on a large number of out of state students.
What does UF have in common with the UC’s? They have a large pool of in-state students to recruit and don’t depend on OOS recruitment (and don’t’ depend on OOS tuition).
Since this is the first year UF will use the Common App, they may be adding the two weeks in anticipation of a sharp increase in (OOS) application. After this year, perhaps UF will consider and move back to the 2nd Friday in February.
