Is there any real noticeable difference depending on how you

Exactly. House painter guy here. No way I'm gonna share tips with this clown.

I do a lot of car audio and use dynamat all the time. I have always covered the surface I want deadened completely in material, never once have I done some pattern like you have pictured. I don't imagine the shape would make a massive difference, however, if you're trying to save money and use less mat I'd lean towards the strips of mat. If you're extremely cheap you can buy roofing stuff that's pretty much the same thing except tar based instead of gel adhesive. it's a mess but it absolutely works and is far cheaper.

It works best as a large single mass than it does as multiple smaller masses. If you don't have enough to do the entire surface, do as much of it as you can in one piece, preferably towards the center.

CLD tiles on 25% of a panel
1/8in layer of high density foam
1/8 layer of mass loaded vinyl

CLD tile dampens vibrations
foam separates the vinyl from the object
Mass loaded vinyl blocks sound

worked in my cars, and my garage

>I have always covered the surface
a complete mistake
any coverage past 25% is pointless
dynamat does not block noise

this is a retarded oversimplification.
1. Adding more mass, regardless of if it's sounddeadener or not, reduces vibration further and also moves more of the vibration out of the audible range
2. If it's a complex part with lots of joints and shit, you definitely want to cover around all the joints, which can be 60% already
3. If you're protecting against direct impacts, like gravel hitting the wheelhouse or rain on sheet metal, any small gap in the sounddeadener will make a lot more noise when it's struck directly
