Sumo vs conventional for a set of 12 or 15 or something

[Evanther]

We know that the gap in "work" done between a sumo and conventional DL at the same weight is not relevant to a 1rm, because success is determined by the ability to overcome the sticking point.

It seems to me that it definitively WOULD matter in a 50 rep challenge, because the sticking point is less important and the total work done plays more of a determinant role in how doable the task is for a given athlete.

^ Am I wrong on this?

If I'm right, then to what extent does this apply on a set of, say, 12 deadlifts sumo vs conventional? Is there any reason to believe that a set of 12 or 15 conv dls slightly more stressful than a set of 12 sumo dls?

One of the reasons that I'm asking is that my conventional 1rm is higher than my sumo 1rm, but my sumo 12rm > my conv 12rm. I don't have a history of training either of these rep ranges with either of these pulling styles.

Thanks as always

Stress is a result of the integration of internal and external load.

External load has to do with weight on the bar, reps, velocity, ROM, etc.

Internal load has to do with the lifter's experience of those elements and psychological factors that influence how a stimulus is interpreted.

I would not expect there to be a significant different in stress from a 12 rep set of conventional or sumo unless someone is way better (or worse) at one or the other due to previous training or, alternatively, has a marked difference in attitudes towards one over the other.
