These are milliseconds.

Not sure. But as Gary suggested, I'll let it sit for a while to see if
it helps.

That's a very good point!
I am using a PD10 currently so yes that explains that offset. Thanks for
pointing me at that.
I'll see if I can flash a PD11 myself (sofar my aliexpress burner fails
to do so) or buy one from Tom van Baak.
