Yes that was me.
I stand by using two decimal places, despite what others think. I was taught that you want to present one extra decimal beyond where you are confident. The reasoning is simple. If his estimate was 2.49 or 1.51, Rockman would say his answer was 2, I believe it would convey more information to say 2.5 or 1.5, and allow the reader to realize that the estimate is between 1 and 2 or between 2 and 3. The idea is that by dropping too many decimal places you throw away valuble information ,YMMV.
