Hi Ken, you are excused
"Of course", I "need" a screaming scary sharp blade
Nevertheless, a reasonable use of field should be achieved, also the ratio of costs and result.
Jason has represented with his post, that he would not not go below 1 micron, because it will reduce edge retention.
Should I defied Jason opinion, the next reasonable step would not be 0.5 micron, rather 0.25 micron, is that not a too big step
Thereof regardless, in your experience, 9 micron for the blade "out of box", as well as for the slightly dull blade is a good start.
Kangaroo strops or Nanocloth, which is more compliant and follows better the convex blade
Should be used for a thicker blade (e.g. Bravo 1), a thicker leatherstrop
Guess while stropping, the weight of the blade is enough, or demand the used, presumably somewhat harder strobs additional pressure
Ken, thank you for your kind contribution.
