I've built and set up enough reels to know. Removed centrifugal when it was a deficit, though more often dialing in shoes for max lure weight. You tune mag brakes at the light end, and you tune centrifugal at the heavy end.
When you need centrifugal is when the spool and line mass has inertia at start up - e.g., 1500C with loaded stock spool - but the friction is still creating brakes when it's no longer needed. However, the heavy 30-y-o spool is also off topic for this thread.
With the old spool it casts like an old Ambassadeur, and that's how you set it up. With a BFS spool, it casts like a BFS reel, and that's how you set it up.
I'm also a licensed professional engineer and a continuum mechanics weenie.
I was casting weightless rigs on Ambassadeur 40 years ago, and could double anyone's spinning cast with the same light weight by making a spiral cast - a centrifugal cast is completely without jerk, and can easily get the 20% higher release speed - if the Ambassadeur centrifugal was engaging, the cast wouldn't go as far. As the cast is going to overhead, you're already feeding line with your thumb, so the spool doesn't accelerate from zero at release. It's just like a trebuchet, but it's a cast you can only make from the corner of a dock or the corner of a boat, but it's also a cast you don't need with a modern low inertia spool.
Let's cast toe to toe.
The snook was caught on a 2.8-g plug imitating winter glass minnows, and cast on Roro-X spool. That night, I was easily casting the lure 130' (across the light at the next dock - my buddy wasn't able to get his UL over there), I can duplicate that distance every cast in my back acre.
