In the age of computer whales hoovering pools great and small, would reducing the takeout make any long-term difference to the non-whale?

I guess another way to ask the question is this: If Track A has a takeout of 20% while Track B has a takeout of 15%, do all bettors do better at Track B or only the computer whales?

I keep going back-&-forth in my head as to whether the whales would just suck up all the extra money on a yearly basis . . . and now my head [i]hurts[/i].
