It is a worthless stat because it completely ignores tp gain. Naglering has by far the worst DPS among GSs yet it is one of the best GSs due to hit build. The value of a weapon during its tping phase has no meaning whatsoever on itself without knowing the WS side of the story.
If the game didn't have a tp per hit limit on weapon with 999 delay, and SE gives a formula that favors high delay like it has been, then it would probably have the worst DPS in the game. Yet if you can WS every 2 hits due to the high delay but high tp gain per hit, it wouldn't be a bad idea if your WS is extremely strong.
