I was informed only very recently of another reason that learning the rules of accenting can be helpful: it can sometimes indicate an augment.
Here are three instances from the Hymn to Demeter:
Line 25, [face=spionic]a)/i+en[\face][\size], impf.act.ind.3rd.sg. of [size=16][face=spionic]a)i/w[\face][\size].
Line 38, [size=16][face=spionic]h)/xhsan[\face][\size], aor.act.ind.3rd.pl. of [size=16][face=spionic]h)xe/w[\face][\size].
Line 95, [size=16][face=spionic]gi/nwske[\face][\size], impf.act.ind.3rd.sg. of [size=16][face=spionic]ginw/skw[/face].
Are these all instances of augmentation, or does the accent move for other reasons? I suspect the first two examples are augmented, although I wonder if the accent for [size=16][face=spionic]gi/nwske[\face][\size] is just the result of recessive tendency.
