my own experience has shown through several ctth efforts where i release as soon as possable after getting my distance set improves the accuracy when dinged, and makes a non-ding error smaller. inversely, if you hold until the dark blue contracts, if you ding it, it is very accurate, however if you do not, your degree of error is greater. i found it makes no differance what club, ball, or distance is involved, it will still work the same just varies a little depending on equipment, and distance.
my nickel hope it helps.
