I too claim to have a simulated runner.
But you are exactly right Fletcher - how would you ever know I wrote the program correctly and took into account all relevant physics?
There are just too many variables programming and then translating a simulation to hard mechanics.
Any claims that a simulated runner equates to an actual one are ridiculous and ignorant.
Yes, I remember you saying you had a runner in wm2d - the difference between your statement about having a runner in wm2d & many others that appear here from time to time is that IIRC you have a gain of many percentage.
Most that appear here are new to the program & haven't accounted for dissipative forces or they are not aware of small idiosyncracies that can cause the operator to suspect he has a real energy gain; such as overlap/iteration errors where bodies overlap too much, or using square pins in certain circumstances - interaction with internal surfaces of polygons are fine if the polygon is open.
The point is that this is a program used in industry
where you didn't build the code, so it has been & continues to be beta tested, so if you are reasonably competent with it, know the pitfalls, & still get a large net gain then it is unlikely to be a programing error - that doesn't rule out human error though, which is why another build in another program such as Solid Works &/or a physical build usually follows.
So, based on that, I'd have much more confidence in your 'runner' than if you'd built the program with your own code - perhaps without access to other programs such as Solid Works you would go the extra mile & build your own from the ground up, in a program & language you do know well, as a further check.
I doubt I'd be building plastic moulds for POC units to distribute without having done some sim building & POP physical building behind me, but who would have confidence if I haven't said or shown, for whatever reason including IP protection for a very simple principle.
