The only part of this which gets complicated is getting the front weight on a back-weighted key. The value of FW as a measure of key balance is that the front weight we read is how much heavier the front half of the key than the back half. As long as that back half is uniform, that net positive weight of the front has meaning. And it is quite uniform, as David Stanwood quickly found out in his early explorations, not only within keyboards but across many different piano lengths. As soon as someone installs back leads, this predictable uniformity is upset, which is why, when doing a action survey, back leads have to be temporarily removed. But as David Love observed, this is not an issue in reading key ratio.
