Nobody suggested you should give less agitation. What I was trying to say was, that 2 inversions per minute should be enough; provided the tank, reel, and amount of air space allow a sufficiently free flow of developer.
The amount that you shake the tank about has got very little to do with how efficiently stale developer is removed from the surface of the film and replaced with less oxidised developer. That's the point of agitation, it's not about giving the film a white-knuckle ride.
