**mpellenberger, last year it looks like PT invites went out one day after the app release date (assuming that first person submitted on day 1 - hard to tell so if anyone has hard data on last years app release let me know!!)
it is certainly possible we will see PT invites coming out on the 19th!! especially since c/o 2015 received on the 18th
everyone start stressing!

old PT info post:
It seems like the stats needed for PT are a bit unpredictable, but it looks like most have either both LSAT and GPA over median, or one over a 75th and one hovering slightly below median. Can't tell if they favor LSAT or GPA more in the algorithm (if they use one at all).
CRS preferences seem to have an influence as well. Someone with v good stats didn't receive a PT invite, then said they changed their CRS preferences to reflect Duke (I assume by saying they liked NC) and received an invite very shortly after.
Based on the Duke Admission results spreadsheet for last years cycle (found at the top of the LS Accept/WL/Denial thread) it looks like about 80% of TLSers than get PT are admitted and 11% wait listed. no data on denials.
