I use an SVST Bevel meter. My guess is the discrepancy is 2 fold.
#1, you measured before cutting the sidewall back and that cause an inaccurate reading (less bevel indicated)
#2, Some skis have an aluminum or Titanal component the upper edge and a magnet will not stick.
As far as base bevel goes, After discussing this in depth with the Designer and manufacturer of the Bevelometer (at SVST) they recommend measuring base bevel with the ski in the vise sidewall/edge up base facing you. And then hang the Bevelometer with the long portion down the face of the base. Measuring the base flat pointing upwards gives an inaccurate reading.
A-man, while I generally agree with you on most points, I have not had the same experience or luck you have had with Atomic skis. And I'm not maliciously going after Atomic (I love Atomic skis), because it's a problem with all manufacturers, but the fact remains the same, and it's neither of the problems you mention above, it's just not correct from the factory, and its not really a big deal, because its an easily correctable problem.
As far as measuring before cutting back the sidewall, this can cause an inaccurate reading, but its rare anywhere but the tips and tails where the sidewall hasn't been shaped and is still very square. The majority of the sidewall usually matches the edge angle because they are cut together during production. Also, many of these skis are capped construction, where the sidewall is even less of a factor, especially in the tip and tail. Furthermore, if the original reading was incorrect, as soon as the sidewalls are properly shaped and sanded you would see a consistent cut on the edge with your file guide or disc grinder so long as they are calibrated and used properly. This is not the case as I explained in my previous post. Only after resetting the bevel do I have an accurate reading with my bevel meter, thus confirming the original bevel was incorrect.
To your second point, the magnet not sticking to the upper edge has no effect on the magnet sticking to the rest of the edge, which is what matters.
Admittedly, I have never measured a base bevel with the ski base facing toward me and the bevel meter hanging from the top, but I just tested it out on multiple skis, at multiple points along the edge, and get the exact same reading as when it is used with the base up and the ski laying flat. I also picked a ski up off the vise while holding the bevel meter in place and rotated the ski as much as possible in both directions and saw absolutely no change in the reading. The magnet sticks to the edge, and the plane of the guide is flat against the base, there's no way it will change based on ski position.
I'm glad you've had great luck with your Atomic race skis. Could it be that you were getting better skis because your boys were sponsored athletes? I don't know, but I'd imagine they're more likely to get hand picked skis?
Also, how many pairs of skis were you tuning and checking bevels on in those 15 years from the wrapper? I'm sharing my experience based on hundreds of skis every year where I'm the first to work on them after the factory. And I'm not talking about elite level race stock only, I'm talking about everything from U8/10 athletes on up, and in every discipline. Again, I don't think it's an Atomic problem specifically, and they are better than most, but still very far from consistent. At least their bases are usually flat and the grinds pretty clean, which is more than I can say about most companies.
