This is one of those things you find out about machine control.
with some practice, you find that by being 0.5mm from the pcb, and
starting the paste to flow and presising the syringe 0.1mm, that some
exact amount is dispensed.
this will be repeated on every occurance.
One thing that comes to mind is the surface adhesion. If the paste
does not adhere to the surface, it will not stick and the next pad
will get double.
But, each of these things are things you can control.
