"Why would you want to maximize flow rates during a 90 production test?"

Depends on what the company engineers want to do and what infomation they need. They will probably flow the well at different choke sizes, till they nail what they consider their optium flow, then go ahead with some shut-ins & PBU's to determine the resivour boundries and a host of other things... Also gives you an insight of future wells in that field and if it is worth going and drilling more. The company may only hold the lease for x amount of years, and so want to suck all they can out of it before the lease expires, so they want to know how the well performs etc etc etc... there are hundereds of factors.
