drift during my session of 200 rds and just tossed them back in

You probably already know this, but if you hit the cancel button only once, you can then zero without losing your count or settings. Pressing it twice wipes the count. Pressing zero without hitting cancel can cause it to auto-dispense with no pan under the nozzle. Don't ask me how I know.
One thing I don't like in the programming is there is no way to cancel the count of a load that went over and you "dump". would be nice to have an "undo" button that cancels the last drop counted.

an "undo" button

I'm not that wrapped up in it, I know how many I have because I'll have so many primers out or a box of bullets... I think mine drifted because I did too long of session before checking zero. I also tried their statement about no electronics in the area and had my laptop at the far end of the workbench, about 8 feet away...started a movie and immediately was wandering up/down two or three tenths. Took it away again and zeroed and was fine again.

All these things you learn talking with other guys about the machines. Reading the complaints about the machines just confirms that these other guys did all the things we agree we shouldn't.
