If you had management experience they will likely consider those as transferable skills if you held the job within 15 years from your AOD. The Vocational Expert rules are exceptionally complex IMO.
If at Recon they denied you based upon your ability to do prior work, then no the Grid was not considered. If they decided you can no longer do prior work, then they would have evaluated the Grid before moving on to Step 5.
I would recommend reading/rereading 3.00 E. It covers all SS requirements for
valid spirometry testing including your height without shoes, legible tracings, etc. One technicality on the way it was reported and you would have been denied.
