Depending on the multiple start timing, the movement amount in order to change the speed to the target velocity of the FB in
buffering may be in short at the target position of the on-going FB. In this case, velocity change is executed immediately, but
the velocity cannot reach the target velocity of the FB that is during buffering at the target position of the on-going FB.

■BlendingLow
The slower target velocity between the on-going FB and the buffering FB is used as the switching speed.
The operation is same as BlendingPrevious when the on-going FB target velocity is slower, and it is same as BlendingNext
when the buffering FB target velocity is slower.
■BlendingHigh
The higher target velocity between the on-going FB and the buffering FB is used as the switching speed.
The operation is same as BlendingPrevious when the on-going FB target velocity is higher, and it is same as BlendingNext
when the buffering FB target velocity is higher.
