Besides the CRS score (Assuming that factors such as ECA with a Bachelor's/MAster's degree exist), is there any other common aspect to the people who got their PT invitations? I saw on a different thread that someone with a CRS score of 404 got an invitation, and this makes it clear that invitations aren't being sent based on one's score alone, especially considering the fact that several people with higher scores haven't received one yet (Again, I'm assuming that the aforementioned people resubmitted their profile after June 1).
