Keyaway for me. If they said that the whole build was 2420 bricks and they previously announced laying rates of 20-30 second per block. Assuming those are an average laying rate through out the build, they are completing whole structures in 13.44 to 21.16 hours. However, those laying rate were stated quite some time ago. If I was to guess they are more towards the 13.4 hours, maybe even lower. If they can achieve a 10 or 15 second laying rate, which is 6.72 to 10.1 hours you are talking about possibly parking this machine once and building 2 house in a day. Taking seconds off each brick laying motion is a substantial piece of driving future revenue, let them play in their shed for now. Getcha' popcorn ready.
