Default how to read a compressor map for tt application?

ok i know how to read the maps and i was just wondering if i plan to run say 20psi of boost with a twin turbo set up and am reading the air consumption graph of a 427 at 20psi...would i then read the map for each turbo at 10psi since i am reading one of the 2 turbos? seeing as i will be running 2 turbos which would actually be 10psi from both right?

see i read that just dont know what to do when going the twin turbo route...just cut everything in half? since i canonly read a map that is specific to a single turbo would the info i use to read that map be cut in half like for an lsx 427 at 6800RPM and 20 psi it would consum 110lb/min of air with a pr of 2.36....so when i go apply this to the compressor map of ONE gt35r turbo then its way out of efficiency so would i have to cut all im info in half like 10psi?

ok im sorry if this stupid but all i cut in half is consumption? so from 110lb/min to 55lb/min? so the pr would go along with this being according to the 427 ls6 graph 1.20 and 3 psi? OR do i just read the compressor map using 55lb min and use the rest of the info from 20psi? so 55lb/min pr2.36 and 20psi?

Cut the mass flow rate (consumption) in half, and keep the same PR for 20psi.
