Batten deflection numbers

[dnus4925]

What sort of batten deflection numbers are there? My top batten in my FO1 is 13.8lbs. That seems a little stiff.

5 lbs, is typical

How are they measured?

[Bob Gray]

The way I do it is to put the batten vertically on a postal scale ( any scale  that will measure under 20 or so pounds accurately like a food scale will work) and press down on it. When it takes a set you’ll have the deflection weight.
