yeah, i did; a couple hours after the original post it was chugging along, blowing over the top of my airlock. i had to switch to a blow-off tube and it's still gurgling away two days later.

Then, you grab a small sample from either a concentrated part or a watery part and bingo, weird OG numbers. Even letting the wort sit a little can allow it to "layer" and if you draw your sample off the top it measures low or if you draw it off the bottom with a thief it measures high.
1.090 vs 1.093 is probably just a volume measurement thing, though.
that's a good point, i can say for sure that the top-off water was not mixed in very well when i took my sample, if it was sitting on top that would easily account for 3 points. well, i'll consider the mystery solved and just hope that my 1.097 wort with an underpitch goes all the way to my target terminal gravity... and hopefully it isn't too estery, i think that's the problem with my pale ale, and with what i'm doing with this batch (adding vanilla and bourbon and aging for a year) i'm hoping for a good result.
