Just noticed your reply.
I said I tested in game, and feel free to test it with official in game testers.
My own testing is under Language Chinese, and can be watched here:
Password: PSBUG
I tested many times, using a min spa (345) Mega Gengar with nomalize, and a 219 Zapdos with Charge, see

And these are the rolls i get in game, which apparently doesn't have the boost. 154, 156, 153, 162,147, 142,136,148,144,148,157,162,144,153,145,147,159,142,147,157,151,148,145,162,142,136,159,150,139
And the PS replay with the exact same SPA Mgengar and exact same SPD and HP Zapdos is this
