You mean this?
But most by numbers judge a poet’s song,
And smooth or rough, with them, is right or wrong:
In the bright Muse tho’ thousand charms conspire,
Her voice is all these tuneful fools admire,
Mr. Pope
I think the technical aspects are but
one part of the whole that ought to be considered and that it would be silly to only focus on them to the exclusion of everything else. As that would be treating the poem as though it were but a watch.
