Hi,

See my latest followup of my post.

With revision 4771, the calculation will slow down.

Also, I found that numerical results by 1.16 and 1.15 are different (less
than 0.1%).  I doubt it is because of revision 4771.  I have modified the
source code of 1.16 to undo revision 4771.  And I found that, without 4771,
results by 1.16 and 1.15 are the same with each other.  So, I question
whether revision 4771 do a better job or a worse job, in terms of accuracy.
