STM32H755 DMA peripheral read timing differs from AN4031, actual hold time shorter, seeking explanation

Hello,I have recently tested the timing of DMA reading data from GPIO on an STM32H755 and found that the required input signal hold time is shorter than what is described in AN4031. I would like to ask whether my understanding is incorrect or if it i
