Ancient Greek Pronunciation

[ⲡⲓⲙⲟⲩⲓ]

ⲛⲟϥⲣⲓ ⲟⲩⲟⲛ ⲛⲓⲃⲉⲛ,

I came across the following video on Youtube:
https://www.youtube.com/watch?v=yCv5dK1DOgw

The author of that video shared a link to a spreadsheet for the pronunciation of Greek throughout history. The spreadsheet also highlights the era during which Coptic adopted the Greek alphabet. The pronunciation during that era mostly agrees with the Authentic pronunciation of Coptic. That spreadsheet can be found at:

or

I thought it might be worth sharing.
