planning scrog setup, please check my math , help

i'm growing in a 3 x 8 area (24ft) and am planning 3 rows of 8 plants (northern lights x bigbud) giving me a pant per foot. the screen has 3 inch squares and is 24 inces above the table giving about 16 inches of veg room before the plants hit the screen. the area is in a reflective enclosure and is lit up with 3 600 watt bulbs.

fist off does anyone think i should do anything differient with the setup , lights, amount of plants,. anything

second in a perfect world 1800 watts in 3X8. can that yeild 1800 grams from 1 watt per gram??
with a scrog setup in another perfect world can i get 2 ounces per ft of canopy.

I have read people making refrence to these numbers as good grows but don't know if this kind of math is more from the dreamer end of things.

all input apperiated.
thanks bh

hi im on my first scrog and had similar questions, i think from what i can gather 2 per sq ft is poss, its all about switching them at right time, i know alot of people like to keep the net a bit lower, i think its because the longer you have to veg for the more chance of it getting overcrowded when you switch, and out of interest running 3 600s, what you cooling with?? im doing a 6x4 but only with 6 plants but going longer veg and they are ppp which has a stretch on it so ive read, so ive decided to keep it easy for me lol

i'm running ducted cool tubes with the 600s and 1 inline fan per table with 2 osillating fans per table as well
thanks for the input
