Duane, you should not believe that! (In fact you're completely wrong and
should challenge what I say.

) Only the picture measurements are based on the 12" wing saddle scale, and it is now calibrated with Bob Noll's measurement. The MAN plan has an explicit scale that is the key to this issue, the RCM&E plan has dimensions. Please re-check my last post.
The measurements in the MAN plan are cross-checked against each other and corrected so that all is consistent. In fact, the wing saddle and root chord dimensions are even confirmed now and we only don't know if the real wing was modified (doesn't seem so). The RCM&E plan is essentially less precise (because it's small) but the measurements were calibrated and corrected using the MAN plan dimensions. Once finding out that the two MAN pages have different scales cleared all up and made all dimensions consistent.
You should not only have a look at the various dimensions in both plans and compare them (what is the same and what is different). You should also check the Myers plan against the RCM&E plan and the kit plan against the MAN plan. You can calibrate your measurements with the nice round numbers in the MAN plan and this way reproduce the nice round numbers in your plans (they are there, and it's easy because the plans are big).
Differences between the Myers plan and the two published plans would be most interesting, if you find some. Actually I thought Evan would do this job.
