learning to read compressor maps, for all you math gurus..=) Options

[presure2]

hey guys i been trying to learn how to read compressor maps over the past couple days, and came across this site:click me for link
now after the injector thing, i know my math skills arnt the greatest..lmao..but bear with me for a sec, im sure someone will correct me if im off on a tangent again..
now with this formula, i came up with this for my 5s:
CFM = L x RPM x VE x PR/5660
L= liters (2.2)
RPM = 3300(when i want full boost by), 5600(when the 5s starts to fall off), and 6600 (for s*&ts and giggles)
VE = 90
PR = 14.7+planned boost(10lbs)/14.7 = 1.68

so that should give me this:
@3300RPM = 193.94CFM or 13.6lbs/min
@5600RPM = 329.11CFM or 23.06lbs/min
@6600RPM = 387.88CFM or 27.2lbs/min
so..is this correct? hahahaha
if it is, i wanna make a excel sheet with all the figures for future refrence..
heres a link to the spreadsheet i made,
airflow spreadsheet
to use it, you just take the PR#for the boost you want to run, and the CFM or LBS/MIN # and draw the lines on a given compressor map and go from there ... this stuff is fun!
