Jacoby effect?

With Jacoby, if I understand XG's dice distribution output correctly, a whopping 30% of the 1296 next two-ply sequences after 13/8 6/2* become a cash if White doesn't double immediately. Without Jacoby, it's only 7.5%, meaning that more than 20% are too good. Actually, XGR++ thinks that with Jacoby, White should double immediately after 13/8 6/2*, making the latter a nice example of a cube provocation play. Without Jacoby, White does not seem to have an immediate double, but the idea of 13/8 6/2* is the same: It's a tactical maneuver for destroying a big chunk of White's cube vig.

At the score, on the other hand, White should probably double no matter how Blue plays the 54, so 13/8 6/2* is just about as bad as the pseudocubeless numbers imply.
