Modes vs, Scales

In the Scale of 'A' Major, when I calculate the 'P.M.S., I count backwards from 'C, to Bb, to Ab, to G, to F, to Eb, is 'E flat' my new 'Tonal Center'? IF so, do I start my 'A' Major Scale, from 'Eb'?, or find the 'E Phrygian Scale, and count up to 'A,... still thinking in Phrygian scale interval degrees?... "

( this is a 'repeat, question that had 'mis-spelling, in the first Title ).

Let's harmonize the A Major scale. We have:

A -Bm-Cm-D-E-F#m-G#mdim-A

The Phrygian scale start on the 3rd degree of the Major scale so for the A Major scale the Phrygian scale start on Cm.

There may be an inherent fallacy, in answering your own question. Upon further reflection, I have come to a further conclusion. The 'Notes on the 'Guitar Fret Board, in the 'Open, Non-fretted' condition, remain static in their 'tuning of forths, with the odd, 2nd string B', which is a 3rd. However: when you set a 'Tonal Center', the note intervals of accessing 'Keys, and 'Modes change, and become fluid.

If your 'Tonal Center' is 'A',5th fret, 6th String, then as 'A' is the new Key, ( Major ), you treat the 'A', as if it is the 'Ionian' / Do-Re-Mi' Scale. Dropping down a major 2nd ( towards the headstock ) ... now on 'G', you treat this as if, it is the 'Dorian Mode, with 2 #'s or 2 flats..b's. Going, ( Up towards the Bridge ), 1/2 half tone to A# ... you are now in position to access the, 'Locrian Mode. "All is not as it seems". The only other 'Criterion' is, if playing in a 'Group', you all need the same understanding, or you will be 'Out of Tuning' Sync.
