Thats a pretty good guesstimation. And again... this shows how important it is
to be sure of ones measurements... a 0.25 change in ratio is kinda an
important detail ... grin...

Still... I think the basic recommendation stands for this instrument... Put
your Strikeweights on a number 7 or 8 curve, and either Frontweight up to the
Stanwood maximums, or move your capline in a couple mm before figuring your
Frontweights.
