As they say, the proof shall be in the putting.

When things finally roll, then will we see if all the correct things were implemented.

As far as I'm familiar with the manufacturing development cycle of mechanical products, I'm fairly sure that many things are not fully accounted for since no official, peer reviewed papers (as far as I've gathered) on testing and prototyping were published/ released by Peter along the way.

We shall see how all the "real" stuff (as we call it in loose shop floor speak) rolls once the products are on the streets.
