Am I the only one having problems with the Impressions on the new report? For any given day, there's a big difference between impressions reported via this report and every other report. This is true, even when looking at SOME keywords, on exact match only. The clicks, cost and conversions match perfectly. And for some keywords it's fine...
could it be that your reports haven't been properly synchronized yet? When you are checking the stats for the day before, are the stats still off?
