Mismatch between HAL and Reference Manual on voltage scale max frequencies

[GG.2]

I've noticed that the frequencies written in the reference manual are different from the ones used in the HAL.

Is there a good reason they are different? Which ones are correct?

I attached a screenshot from page 407 of the reference manual.

And a screenshot from github stm32u5 HAL stm32u5xx_ll_utils.c

Thank you
