There are other stats for this, but I wanted a straightforward number to show the rate at which a player is accumulating WAR when he is on the field. This won't necessarily show what a player would put up over a season because some guys splits will show they are platoon players, etc. (200 plate appearance minimum).

IMO, it helps compare apples to apples, for example: 

Aaron Judge had 4.9 WAR with a 6.577 WAR/600 (he has 447 plate appearances)
Francisco Lindor had a 7.3 WAR with a 6.39 WAR/600 (he has 685 plate appearances)

The formula takes their WAR divided by their plate appearances and shows us the rate a player is accumulating WAR assuming they got 600 plate appearances (rather than comparing two guys with 300 and 700 plate appearances)

It is valuable for seeing who was most valuable in the time they actually spent in the game. A decent way to look for what might be those hidden gems (or turd covered quarters).

Formula:
(WAR/PA)*600

It basically says if all players had 600 plate appearances and performed at the same rate they did in however many plate appearances they actually had, this is how valuable that performance would be over 600 plate appearances. Apples to Apples.

Anyways, the list includes some lesser known names and I don't have time to research them all, so if anyone sees any names that stick out to them as players we should pursue, I'd love to hear about them...

This is how it shakes out:
