Northern brewer cream ale

Hello i am wounding if an fg of my cream ale is 1.005 now is this right for this type of beer. It was a northern brewer all grain cream ale kit i did a 1L yeast starter an keep aeration it with my air systerm. I mash it at 152f but try to get to 150f like the recipe said to do but 152f it was. Did the boil for 1 hour chilled put in freezer to chill to pitching temp which was 62f but i pitch about 2f below that. took yeast starter out the fridge pitch cold an it was fermenting at about 5hour… Basic i asking is it possible to get 89% attenuation with wyeast 1056

What was the OG you measured?
What temperature did you ferment at?
