I try to maintain the form, but most of the racquet speed is going up and across. I (should) get a lot of spin and generous net clearance. I find this super helpful for grooving the form. If I can get that happening then I get more pace by turning my shoulders more powerfully and closing the racquet face a bit more to lower the net clearance.
If I'm in a "real" rally and I just want to hit more spin then it's like you said - it's actually feels like a faster stroke. I try not to take the racquet back quite as far and really try to get below the ball with the racquet head and my legs.
I see what you are saying and very good points. Thanks for the clarification.
