I'm sure from your previous post you have the knowledge to run the calculations. The oil system losses (bearing clearance leakage) are a non-linear unknown variable that will turn your well intentioned calculation into a ball bark guess.

It looks like Katech is adding the squirters only to LS7 engines. LS7s have a very healthy flowing pressure pump to start with (they also have a scavenge pump), the pressure pump will actually flow so much so they can fill an upper end with oil on a high G sweeper and cavitate the pump on an 8 quart system. In 08 or 09 the LS7s got the 8 quart oil tank increased to 11 quart.

 

When my PCV system was messed up, I was oiling the tops of the pistons pretty good. With the results I was getting (detonation, fouled plugs), the bottom is probably a better idea.
