It is board dependent, some board may has a big capacitance, the off-on-delay is to give enough time for the capacitance to leak its voltage.
Ok, but not clear from your comment if you agree with my change or not.
I think remove it is not correct, the exact time should be measured using oscilloscope, removing it might make sd3.0 not work. But anyway 20000 seems too large a value.

Please clarify.
