I'm of the same opinion as
@mlesemann of course.
As a spec writer, I may write in a parenthetical so as NOT to disrupt my FLOW but I would rarely LEAVE it as is if it's actual action. Eventually however, you tend to teach yourself to no longer write that way.
Having said that? I've seen many shooting scripts that contain lots of parentheticals but as we've discussed here many times... That's a shooting script. Unfortunately, most specs I read of people trying to break in tend to emulate shooting scripts because that's what most people attempting to become screenwriters can find online.
And of course... As we've discussed many times before... If you're shooting something yourself? Write it any way you want. Place as many or as little parentheticals as you need wherever you want them. In a spec though... Especially when it comes to marketing time? I think you'll get more mileage out of your spec if you keep parentheticals down to a complete MINIMUM.
For instance... I only use them when there are more than two characters speaking to each other. When it's NOT obvious, you might place a (to CHARACTER WHOMEVER) parenthetical below the character cue.
Or... If your character's speech fluctuates and it's IMPORTANT to the scene... i.e., (trailing) or (trailing off).
In other words? If WORKS in an action sentence/paragraph? Probably best to stick it there.
