Turn on Button Tempo
Use L2/LT + Options/Menu to open Rift. Move with D-pad Left/Right to Button Tempo and turn it on with Up/Down. Then open Tempo MS. This page is visible when Button Tempo is enabled or Auto-Green is set to RHYTHM.
Use Tempo MS, not an old Rhythm Speed preset
Current Rift uses a number for Tempo MS. If an older tutorial shows Slowest through Fastest, those are old menu labels. Up/Down changes the numeric value; the 10 ms modifier helps make larger moves, and 1 ms changes let you fine-tune. Auto Green MS is a separate setting, so leave it alone while testing tempo.
Run the Button Tempo Value Finder test
Select Value Finder, press Cross/A and choose Button Tempo. Follow the shot prompt, enter FAST, EXCELLENT or SLOW, and use the on-screen no-tempo option when you did not get tempo feedback. Do not guess a result just to advance the test. SAVE MS applies your chosen result.
Save one setup before testing another
Keep the same player and jumper during the test. Note your profile, mode and Tempo MS. Save and close the main menu with Circle/B. Keep your main profile unchanged when trying a different jumper in another slot.
Why it belongs in the same script
You do not need to buy a separate tempo file. Rift includes Button Tempo, Auto-Green, Value Finder and three saved profiles, plus Hub access and lifetime updates. That combination is why Rift is the best overall NBA 2K27 Cronus Zen script.
