The odds of matching to residency are very dependent on the school of pharmacy you are going to, while the top schools match above 90%, the lowest schools match at 20%, so it's still a good idea to start job hunting before the match because there are hundreds of pharmacists getting the news on the exact same day. 

If you need my help in Phase II, you can find my website here, I expect there will be close to 700 open positions after Phase I.
