That's not the point I took from his post, but what a tuner can do is only to extract whatever a given load has, in a rifle, in a given condition..from it. IOW, if that load will shoot dots at 90°, a tuner can make it dot up at 70°.
FWIW, seating depth does not seem to be that critical with a tuner. I've been very fortunate to win a lot of matches and haven't chased the lands, essentially, since I started using a tuner...in 2008! That's pretty huge! This at least implies that tune is about barrel timing..bullet exit with barrel position in its oscillation. If that is true, then it also applies mostly, to powder charge. I have found this to be true, fwiw.
No, we're not comparing hof points here. We're comparing results on paper to confirm what was seen on an oscilloscope during vibration analysis. The two combined, still don't equal your hof points. That doesn't mean it's useless information either, Bart. Maybe this was a case of one or both of us misinterpreting his post.
