I don't use the UDA as far as I can see - for me, there is high-measure
continuance of OM's physically compatible with the one I have now because I
am in a physical universe, and this universe (quite likely as part of a
multiverse) is one of the simplest compatible with the presence of SAS's
(hence having high measure by the minimum specification argument).
(Perhaps I shouldn't have let the following pass uncommented upon:

To which I should have said something like:
It is important to distinguish an entity (in this case u-reality) from what
can represent it (bit string, mathematics etc). I would call u-reality
'ontological', rather than 'concrete'.)
I have been OK continuing with this thread where it involves defending my
own ideas, but as I have hinted several times I don't really feel justified
in commenting on yours at least until I have taken another look at your book
(with the help of your remarks in this thread - thanks for these). We have
at least established that there are fundamental differences between the two
approaches.
