The saved hold answers when a sequence moves on
For normal OneTap, RELEASE PT is the saved hold before the release sequence. Button Shooting instead selects SET TIME, MOVE TIME or FADE TIME for its shoot-button hold. These fields are not the same timer stored under different names.
A consistent saved hold that releases early can support a small increase for another comparable test; consistently late can support a small decrease. Before doing so, confirm the correct input, context, environment and active slot. A changing test cannot identify one timer.
A manual release belongs to your hand
For manual Tempo Lock, hold Square / X and choose when to let it go. For RS Tempo, move the right stick, hold it, then return it to centre. The physical release or return is part of your input, rather than a hold chosen by RHYTHM TIME.
If manual release feedback is repeatedly Early, compare letting go later. If repeatedly Late, compare letting go earlier. Keep RHYTHM TIME fixed until the physical release is repeatable enough to investigate separate tempo feedback.
The transition has its own evidence
OneTap uses INSTA TEMPO for its release-transition setting. Manual Tempo Lock and RS Tempo share RHYTHM TIME in this reference. The menu value shapes the transition; it is not a direct replacement for the saved standing hold or your hand's release moment.
Record Fast / Excellent / Slow separately. Changing a hold and a transition together makes it difficult to know which change affected the next attempt. Keep Human Mode, Human Tempo, Human Variation and shot context constant during the comparison.
