Combining Stats always has me skeptical. Rather compare each stat separately. Then I can rally compare the true stat.
Combining number shows me at least you can play with numbers.
Guy has a terrible BA, but a good OPS has me skeptical.
What is it, can he hit, or cant he? Can he do the simple thing of making Contact.
If all your looking at is Power, then that is too one dimensional to me.
Can you imagine all these Great hitters who could do both hit for Average and Power, did just one thing, swing for the fences.
Ted Williams probably never hit .400+
Mays and Aaron hit 900 HRS.
Boggs and Carew probably 30+ HRS guys, Rose at least 20.
Don't go by slump, go if he is 1 for 20, go by if the one hit was a HR, and he had 7 walks within those 20 at bats, with 8 strikeouts.
Then look for how many Left On Base for those 20 at bats. Because batter didn't make contact. Which lead to losses.
Just as soon look at all separately, did that for years.
Not too hard to figure out.
