Two questions:

Is Samson's Dynasorb a double braid? I'm assuming yes based on what I know but have not seen it explicitly stated anywhere.

Is it possible to splice 10mm Sirius cordage as a dbl braid splice? I've found toufelburgers instructions for the larger diameters of Sirius rigging lines, but they don't list the 10 mm in the instructions.
 
i‘ve always used a regular double braid class 1 splice for the 10mm sirius and used the taper pattern for the cover from teufelbergers sirius splicing instructions.

dont know anything about dynasorb.
 
Is Samson Dynasorb II the same as Nystron? Looks like both are polyester cover with nylon core?

If it is, then its a double braid. I use a standard Class 1 splice. Below is 3/4" Nystron

I emailed Samson and they said nystron and dynasorb are the same. Dynasorb is an exclusive name for Sherrill/VSG

Yes same as typical double braid splice. Cover taper count is a little different as it's cover pattern is different.
I use a cover taper pattern of 5, 5, 5, 5, 5
 
I could never figure out why you need a specific tapering pattern for the cover tail on class I double braid splices?
 
I would guess just to keep it from unraveling so burying it in the core is easier? I always bury the cover first and then remover strands to taper it anyways.
 
It might also be so that the remaining strands are pulling the circumference of the cover equally, and not from just one side?

Makes sense that it should be symmetrical if possible since the weak point is where diameter changes. Keep that change as uniform as possible to max results. I highly doubt that a "lopsided" cover taper would catastrophically reduce the strength of the splice though. When talking in terms of life support though, max results is what the goal should be.
 
I generally eyeball the taper as well/usually do half the cover strands before inserting the cover into the core then finish the taper when its sticking out of the core. To me, the key measurements are the number of cover strands between the eye/crossover and how many strands between the crossover/start of taper.

From my notes:

From the eye mark , skip 8 strands for crossover then skip five before pulling first pair for taper. Then 4, 5, 4, 5
