Ender 3 S1 Pro Vref adjust

Ender Series Creality Ender-3 S
1

Hi all, I am looking for information on the correct Vref values on the Ender 3 S1 PRO.
I have a S1 (not PRO) and I adjusted the reference values according to Creality’s video and it works perfectly. I purchased an S1 PRO and performed the voltages check and the values seemed to me to be too low. Accelerating a little the printing I have lost steps, which leads me to suppose that they are values that are not correct (of course, having checked that mechanically the printer is well in all settings of eccentrics, spindles, belts, etc).

I searched several days for information and the truth is that it is quite confusing, and I go to the official forum to get out of these doubts.

Can someone from Creality inform me the CORRECT values for this printer model?

Thanks in advance.
