WARNING: HEAVY SPECULATION

I do not think that Kirito went all out on Yuuki. My reasoning is that it has been stated numerous times that Kirito loses some aspects of awareness when going all out and also has difficulty recalling details or entire periods of said outbursts. However in Mother's Rosario, Kirito was able to recite a sentence from mid-battle with Yuuki. From this it can be seen that Kirito was holding back to some extent. On two unrelated side notes, Asuna wouldn't have survived Mother's Rosario if she didn't retain her SAO stats, as stated in ME7, and that XaXa had a weapon of at least equal quality to Kirito's in BoB, the only reason behind the vastly different outcome being Kirito landing a direct hit with a high-damage sword skill (Double Circular) and not XaXa.
