To make is easier to understand
The Homing Feed Rates look like this. {50*60, 50*60, 4*60, 0}
This is in mm/min but this person like working in mm/sec, multiply your mm/sec by 60 seconds and your back to mm/min
Steps Per Unit" look like this. {78.7402,78.7402,200.0*8/3,760*1.1}.
The Z they have left in some of the maths, 200 steps per revolution, * 8 to account for the micro stepping, 3 is the movement per rotation
Ether style can be used, the compiler just does that math for you
