How Much Bigger Are the Groups on PotD Compared to Veteran?

Does anyone know how big the groups are in PotD compared to Veteran, on average? I haven't made it past the Dig Site on PotD but it seems like there's definitely a lot more stuff in the Sea Cave (An extra construct, a Rotghast over in the undead area), and a lot more boars and wurms on the way down to the central pit with the Drakes and Panthers and such), but Gorecci Street looks to be about the same, numbers-wise. 

For me, I'm actually not a fan of how much enemies on PotD soak up damage while brutalizing the party, but I like encounters with more than just one or two enemies. That's why I'm hoping to figure out how anemic the encounters are in Veteran compared to PotD.
