How accurate are delays within loops

Topics merged.

I'm really fed up having to tell people not to cross-post.

OP, you had two threads asking the same question in different parts of the forum.
Did it not occur to you that other people would answer in one thread and not realise that someone else had answered it in the other?
Don't you realise this wastes their time?
How do you think it makes that person feel?

DO NOT CROSS-POST.

CLEAR ENOUGH?
