Hmm, interesting concept looking at forms akin to music pieces.
No, I don't count the moves OR the time between the movements.
It is more kinesthetic ie about feel and precision of movement.
Flow here is more about ability to maintain structure during transition of movements, all the while listening to yourself in terms of reducing tension, stiffness, maintaining balance and driving energy through the appropriate structures.
