question on hole size on inlets to a double acting cylinder,

[lamanated]

picked up a 2" cyl today and while flushing it out, I notice one of the two inlets has its hole smaller drilled ,, I'm guessing its to balance flow rate for the ram side vs piston side?thx

It is possible the rod end inlet could be smaller do to space constraints and lower flow rate required during the extend mode.
