Damn you are all over the place boiii...
Goku > Tao Pai Pai > Goku Vs Devil (Initial) > Devil > Goku (vs Mummy) > Mummy
If he's stronger than Akkuman, he wouldn't be shitting his pants so much against Tao Pai Pai. Also, Akkuman shouldn't be too far away from Tao Pai Pai's initial strength. So no, I don't think Black is quite up there.
But you do make a point, surviving Goku's attacks at all is big, but I doubt Goku used the full power he used on Akkuman, against Black. That's pretty clear. Goku can't expect Black to be strong enough to take that.
