My homepage says that I received 100 HU in both passive and HyperDrive rewards, why do I only get 95 HU in my Rewards account?

Please be reminded that 20% of HyperDrive rewards (Unilevel/VIP bonus) goes to the Certified account.

That is to say, if you get 10 HU in HyperDrive rewards, 2 HU goes to the Certified account.

Because of that, you will need to manually exclude 20% of Hyperdrive rewards from what is shown on the homescreen.
