I moved the issue back to the Editor state.

	Thanks Shalom. So, I shall not file any mantis.

		What apparently happened in 1777 is that there were
several versions of the proposal. The original version did not change
this text. Version 1800 18-4-1 update proposal_b.htm
<http://www.eda.org/mantis/file_download.php?file_id=1899&type=bug>  and
the following versions did change this text, but the changes were not
colored, and nobody, including the editor, noticed that this text is not
the original and needs to be colored. In the final proposal, the text is
		 
		"the above sequence causes transition bin b2 to be
incremented on the 8th sample (3 nonconsecutive twos), and transition b3
to be incremented on the 6th sample (3 nonconsecutive threes).
Likewise, transition bin b2 is incremented on the 10th sample, and
transition bin b3 is incremented on the 9th and 11th samples. Transition
bin b5 is incremented on the 15th, 16th, 17th, and 18th samples.
Transition bin b6 is incremented on the 12th sample.  Transition bin b7
is incremented on the 13th sample."

		Since the proposal does contain the intended text, and
the only problem was not that it was not colored, I think this can be
dealt with purely editorially, by putting the issue in the Editor state,
and adding a bug note stating the corrections needed.

		Thanks,

		Shalom

			Swapnajit --
			
			I think you are correct that something went
wrong here.  Mantis 1777 changed the sequence of sampled values, without
-- as far as I can tell -- altering text about bins b2 and b3.  The
behavior of bins b2 and b3 used to be straightforward because the
sampled values 3 and 2 alternated, and I think that behavior would
change with the new sampled values.  Take a look at Draft 4 (or the 2005
standard) if you want to see how it was before.
			
			Important note: I can't open any of the HTML
attachments to Mantis 1777, including the final proposal.  I can open
the PDF attachment of an earlier proposal.  The modifications were
introduced in Draft 5, so you can infer the approved proposal from the
results.  The Mantis proposal was written by Don Mills.
			
			I think a new Mantis is necessary to clean this
up.  Will Cadence be filing one?
