The consistency of the Neos 1000 tension is no LESS precise than a drop weight or a electronic constant pull machine assuming that all are calibrated correctly and assuming that the electronic machine is not one that has the over shoot situation. (mine do not)
The consistency that you speak of is coming more from the stringer regardless of the machine. I own and string on several different types of machines and can easily reproduce the same string bed stiffness regardless of what machine I use.

The fact that the Neos 1000 does not have 306 degrees of rotation is more of a benefit than a negative. As a result of having the tension head located higher, is the primary reasons that you do not have to add 10% of tension when comparing it to a electronic constant pull machine this is because the string is being pulled straight from the string hole with out causing any friction. If the tension head was positioned lower allowing for 360 rotation the tension head would be pulling the string out of the frame downward causing friction causing tension loss.
While the Neos is not the latest technology it has the ability to support the frame and provide consistent string job. The reliability and convenience of the machine's functions, including calibration, and the overall quality enables it to be so user friendly.
The Neos 1000 has been a bench mark and the industry leader, a work horse without any problems for many decades.
I think you're glorifying the NEOS a liiiiittle bit here. I agree that the stringer is as big a variable as the tensioner (if not much, much bigger), but since the tensioning system of a crank relies on the operator, there is a consistency variable regardless implied. Saying that there's no need for a 10% compensation is also a little extreme. The 'rule of thumb' of 10% is due to a systematic difference, not strictly as a variable of pull angle. CP machines often have 360 degree rotation, thus they pull at a lower angle, does this mean the 10% rule of thumb should have an asterisk with it? I don't personally think so. I also think that the overshoot issue is more minor than we commonly discuss it to be. If the tensioner overshoots and then comes back to reference, all within the time span of <1/2 a second, I don't think there's any issue other than any systematic difference. As we all generally agree upon, provided the operator is consistent in their process, the only thing that really needs to be considered is ones' reference stiffness/tension delta versus another operator.

I've heard great things about Stringway though, and I have no doubt they're good quality.
If you ever get overly curious, I got a buddy in your neck of the woods that has possession of my old MS200TT DA system. Just let me know, I can grab his machine and let you demo.
