Have you built these three designs or are they simulated?
Simulated and real world designs will differ slightly due to tolerances in your components and how they change under various circumstances, like increasing temperature. Resistors and capacitors chosen in simulation cannot always be easily chosen in real world designs as manufacturing every single possibility of resistor would be pointless. Instead ranges based on tolerance are manufactured, meaning real world designs might be slightly different.
If you haven't built it, it might be an idea to have a look at what actual components you would use if you were to build it and the tolerances attached to these components to show how accurate your design is.
Hope this helps in some way.
