Ways to delay a macro for less than a second (no Macro Wait)

Sometimes I need to include a small delay in a macro, but Macro Wait 1 is too long. I've found that Macro Wait 0 works pretty well. You'd think that Macro Wait 0 makes no sense, but I suspect it does some (useless) clock or background process initialization in the background, which makes it delay the macro execution just a tiny bit. Stacking multiple Macro Wait 0 calls does work by the way.

I was wondering if there are other less cheaty ways to delay the macro execution just a tiny bit, in case Macro Wait 1 is too long.

On a side note: the reason I need Macro Wait 0 is because putting Sub 161 @ 100 + Sub 161 @ 0 directly next to each other doesn't work. On one hand it does what it says, but on the other hand it doesn't correctly make Sub 161 the controlling target of its contents for some reason. I wonder why?
