In other words, by the Koine period, did ALL the accents denote stress or was it:[*]acute = stress[*]circumflex = stress[*]grave = no stress?  These question seems important to figure especially when it comes to phrases where you have a bunch of words one by one that have grave accents--it sounds very monotone and awkward. I'm finding that sentence flow seems smoother when the grave accents are stressed.
