Phil 3:7 wrote:Ἀλλὰ ἅτινα ἦν μοι κέρδη, ταῦτα ἥγημαι διὰ τὸν Χριστὸν ζημίαν.
Yet whatever gains I had, these I have come to regard as loss because of Christ. (NRSV)
But whatever were gains to me I now consider loss for the sake of Christ. (NIV)
But whatever things were gain to me, those things I have counted as loss for the sake of Christ. (NASB)
But whatever gain I had, I counted as loss for the sake of Christ. (ESV=RSV)
So the Greek perfect gets variously translated as an English perfect (NASB), an English simple present (NIV), an English preterit (ESV=RSV), and a periphrastic perfect of result "to have come to" (NRSV).
This is a difficult and subtle case but I think that the NRSV does the best job of conveying the nuance of the perfect here.
