Is having 3+ of the same subs pointless?

[LupusFreak]

So I recently acquired a part-time pirate shirt via Spyke with 2 ink recovery ups. When I added another slot to it, I got an ink saver main.

I was planning to use it in this set:


Mawcasins
But when I started messing around in the testing area, I noticed no difference in ink efficiency when I switched back and fourth between the Part-time Pirate and my Anchor Sweat ( ).
My question is, are the diminishing returns so small after 3 subs that it isn't worth it? I have a fit for mini splatling with four run speed ups, and was wondering if I should tweak that too.

The diminishing returns don't kick in (very much) until you're somewhere around the equivalent of 3 mains of an ability. Triple gear is very popular.

Depends on the ability and the weapon.
