I asked the question because I might want to build one of there but I
could not see how they coud be stable with just an RC filter.  So the
answer is "they just are".

OK, so they are stable but why would it run at 10+16=26 and not 10.01+15.99=29

And what happens if I want to build a 10.01 reference clock?  Could I
do that with a regenerative filter?
