well they started in October.. the odd day here and there... so far they have done 640 blocks.. and have a total time of 80 hours on the job.. thats 7.5 mins per block on average... okay, they may have to cut a few and measure up for 1 door / 2 windows... and mix cement.. .but even if that took 1/3 of the time.. it's still an average of 5 mins per bock!!...
