I think I located and corrected two errors. Can anyone explain how the turbine housing A/R affects the compressor map?

I’ve modified a turbo sizing workbook I found on the internet. The modification allow for 8 operational scenarios to account for altitude, target HP, OAT etc. Each scenario provides a corrected airflow and pressure ratio needed to select an appropriate turbo. The workbook may contain errors so I’m sending it out for input. Hopefully Ed or someone can validate the formulas and those flying turbo aircraft will commit on real world experience.
