I think bud structure factors in when considering how long to dry too. Hopefully you got nice fat, dense buds and it'll take a little longer to dry. But if they're not that dense it can be really quick.
I had some RA-damaged plants (poor yield, loose buds) and they were pretty much overdried hanging for 3 days and then straight to jars. However, the unaffected plants (fatter, denser) went 4 days hanging and into jars and they're PERFECT so far. Just put them in jars and they're still sticky... It's amazing how big a difference drying/curing makes on taste/burn!!

TBM, thanks for posting that! I was looking for it forever and couldn't find it then I found it on ICMag... very nice method if you've got any uncertainty. I picked up two of those little ones at Walmart (6.50 ea) and they're indispensable! I put them at the bottom so they don't crush my buds!
