No accumalator spring.. do or dont

Shocks don't cushion?? Good ta no..
Sure.. whatever.
Question is, when you select 2nd gear, how long does it take to move the accumulator in the other direction, especially when the valve body has been modified to facilitate oil flow and it's aided by a spring?
How far does it move? How much oil does it take to fill it and dump from the other side?
If the restriction in the accumulator oil circuit is more than the ones in the 1st to 2nd shift circuit of a modified valve body would that also reduce it's influence on the shift quality. Would the 1st to 2nd circuit go to full pressure before the accumulator gets a chance to cushion it?
These are things to consider.
