I'll try and explain it better and then see if I can draw it .
Test 1
2 masses dropped from identical heights at the same time dropped on spring board as per your initial model. ( record start height.)
Run sim (Record end height of both end heights).
This will give us gained or lost potential energy. ( Mass A + mass b ending height, Probably a small loss) record result.
Test 2
2 identical masses drooped.
Mass A dropped from 1/2 the height mass B.
Mass A is dropped 1/2 a second before mass b. ( See my slam dunk video)
This will give mass A time to compress spring board as mass B falls and accelerates.
Run sim. Calculate end point of both masses. My theory is that
1 ) that test 2 will end with total higher potential energy than test 1.
2) that test 2 ending potential energy ( expressed as ending total height of both masses will be greater than beginning height of both masses.)
If this is correct we have an increase in the Ending height (potential energy)of total system which according to newtons laws is impossible.
If this would not qualify for a valid test of Newton's laws please someone say so and explain why and I will reconfigure .
Ok going to try and draw something to help explain.
But that's part of both Science and part of perpetual motion design (see how it may beat current science).
I predict for Test 1. They end up at the same height as they start.
The spring is compressed and behaves as if you drop a single mass with the combined weight. So we should be able to manually calculate how much the spring gets compressed given:
a. the total mass of those weights
b. the height of which they drop
c. the elastic behavior (say: a spring constant in units kg/s²) of that board.
For test 2: It absolute qualifies as a valid test of Newton's laws, and also Hook's law.
Already showed how that works, now find the formulas or figure out some practical test or tests... (hint: I'm sure your iPhone has a camera, there are 'apps' to view individual frames of a video)
I also explained that verification is a necessity: So please check if, when or how I may have tricked you... or otherwise see if you can correct, enhance or improve what I showed.
The following message applies too:

First try test 1, then test 2.
And good luck!
I have aprevious engagement with large amounts of alcohol and a certain beautiful woman
Forget the alcohol and just ask if she can figure it out?
That should be fun!
