It would increase deceleration the real benefit is reducing load on the engine accelerating by a small amount

It’s a 210 amp alternator…say the running load is 30 amps..then on acceleration it would only switch off that 30 amp load ..about 0.5 hp..on de acceleration it could put 120 amp in temporarily..so that’s about 4 hp of braking..

In a 200bhp + car quite trivial but shows the lengths they go to..
