Reminder that Trusova performed the actual optimized layout for 2 different quads... Optimized layouts will be a thing, these aren't "layouts no one can do" if Trusova just performed one.
By not doing -3Lo combo you only lose 1 point. So in that case, performing a second 3A would only be worth 1.34 points more with your layout. Is it really worth it, even at that point? I don't think so, to me the risk of failure or poor GOE on a 3A far outweighs 1.3 points in BV.
I strongly believe that repeating a 3A is almost never a good idea. The benefit over just doing a single one is minimal. Only if the 3A is at a rock solid, stable level is it a good plan. But at that point, a quad would be far more potent still and with such a comfortable 3A, could be possible.
