I have 2 isssues with the Prusa firsl layer calibration wizzard. The line which may not stick to the bed due to poor addhesion and has nothing to do with the Z height and the square, which is too small to see in real time, if it is ok or not. Only with the nozzle out of the way, you can see the square. So I designed the squares big enough, so you have enough time to adjust the Z and double check, when it moves to the next one. Also it is the full bed, since in the middle you get always perfect results, but at the ends because of lower temp and warp you could have problems. 

How I proceed. On each square I go lower by 5 untill when I touch the square it has rough surface. Then I know Z is too low. I take the value from the results, whick looks the best and make a second run for all sqaures, so I can check if the result is same at the edges as in the middle and then adjust accordingly.
