True, but the calculations are based on real-world laws of physics. I'm not saying certain things are impossible, you can always empirically achieve theoretically diffcult things - like milling Aluminum with a Dremel - but how long will those bearings last, how does the accuracy drop off as the runout increases, how hot does it get before the poor thing melts, etc... There's no harm in understanding the limitations and designing around them...
All I was trying to show was that the fact that 30mm end-supported rail isnt as good as 12mm supported rail under a range of common tasks that a router/mill might be designed for - which we already knew empirically. I agree "suck it and see" is a good teacher, but equally if I don't have the personal experience I don't take someone else's word for it verbatim without some level of research into the issue. :D
