Having Biology at V doubles the Duration of that Booster.
The BY-810 Implant gives another 10% Duration for the Booster.
So you can double the SP Numbers above.
Edit: I’ve just tried it with BY-810 and Biology V. It gives you a total of 660 Hours of Boost aka 27.5 Days :
Best Thing is, you can change your Implants and the boosted Time remains the same. So you only need the BY-810 Implant when you consume the Booster.
