One would think if the blow holes did not add much a pencil pusher at the factory would realize they could have lots of man hours ($) by just using dimple tape.

Another claimed, but I don't know if it was ever proven, benefit of the blow holes is that even if they are behind the leading edge of the laminar bubble, they can still "blow out far enough to burst the bubble and get the advantage of not having the high drag, laminar bubble" whereas, turbulator tape inside the bubble does nothing at all for you.

It is all about how much are you willing to do to get that last half percent.

Half a percent? One minute on a three hour race? Plenty are won and lost by less than that.

It won't make any meaningful difference to whether you can stay up, or even whether you can complete a task.
