That's been done, actually. Well... Maybe not bricks, but I do recall remote controls that had a couple of steel bars in them that seemed to serve no other purpose than to add weight.

Or, just plonk different things on it and see what does, or does not, change. The only thing that can lie better than a politician is a simulator. Build it and measure it. Heck, maybe that dark ale bottle really does make a difference.

I was commenting to Pete on seeking verification from bananasplit sim using Comsol Multiphysics.
And yet, IMHO, it is good advice in general. I use Multisim and LT Spice myself on the initial stages of any design to get a broad feel for what should happen and just about always the final behaviour will be different when the circuit is actually built. I really wasn't aiming the comment at you so much as those I see going back and forth for hundreds of posts arguing sim results when no one has bothered to just build the damn thing and see, There are topics on this site where someone has posted a legit, well behaved circuit and there are literally hundreds of follow on posts from those who claim to have improved it so much - without ever putting their ideas into actual circuitry. Simulation is nice but does not include 99.9% of the parasitics by default - and anyone who is serious about circuit design knows, you can have the best designed circuit and the parasitics will invariably bite you in the a$$.
OK, rant mode off - just got through reading one of those threads and was still worked up over it. 😡
