You also forgot to mention that all the BGDCP”T letters have a different pronunciation when there is a dagesh qal in them, and when their isn’t. Not just BPC and T.
That means Gimmel and Rimmel (pronounced like the israeli reish, while the reish, which is a dental, should probably be trill or tap)
and Daled and dhaled, so that we can properly extend the D in ehadhhhhhh.
