Trouble is you're comparing a time when Emery had lost the team and was having a nightmare and when literally noone was happy, so years there's a marginal improvement on a guy who was struggling badly, that's not a good measuring stick, he should be doing a lot better.
I personally feels even in those 16 games he's shown he doesn't really know what he's doing and also you have to ask how he's turned a team with so much firepower (that's our strength) into a team with a tootless offence.
