Down FP measurement

[lightofnord]

I made the measuring cylinder
The black mark on the rod is zero and one red mark is +100 CUIN.
So the measured sample is ~300 CUIN.
Yesterday night I washed out the down, now is drying. Lot of fine down particles came out
After drying I will make a new measurement, I'm curious there will be any differences or not?

Edit:
Sizes and weights in "US 2000 norm" based on article: https://en.wikipedia.org/wiki/Fill_power
Cylinder diameter: 241 mm
Compression cylinder: non-mechanized cylinder of 68,3 grams.
Mass of the sample: 1 oz = 28,4 grams.

Following this, may be first time I have watched some one actually try and measure FP (and post it)
