Juan Carlos went over Section 1 on General rules.
Question and discussion on final summation (Section 1.3.4): Ssuggest adding some time between presentation and vote
1.3.4 Final Summation

Option 3) Q/A panel for a group of 3-6 proposals (in favor: 10)
Dropped the panel option and kept 5 min option (option #2).
Section 1.5.3. Last minute changes
Question: Do we require a preliminary presentation also be uploaded together with proposal document a week in advance? It is helpful to see the highlights.
Question: Ddo we encourage borrowing ideas (not willing merges)?
No objection to require uploading presentation along with the specification.
Juan Carlos went over Section 3: Rules for July meeting.
Discussion: Wwhat is the purpose of initial down selection in July, comparing to just traditional low hurdle vote?

Session II, Tuesday, May 17th, 10:30-12:30, Cairns Conference Room– Meeting Room #3

Juan Carlos continued reviewing 274r5 (a cleaned up version of r4 with changes from last session), starting with Section 3 (Rules for July meeting)
Discuss presentation time allocation rule
Nobody speaks in favor of option B, so alternative B is dropped.
Straw poll on remaining two options:
In favor of equal time (in favor: 7)
In favor of alternative A -- more time for full proposals (in favor: 30)
So “more time for full proposals” is accepted in the document as the rule for presentation time allocation.
Going over rules for Sept meeting
No objection in using the same presentation time allocation as in July (more time for full proposals).
QuesitonQuestion: Aany consideration to drop partial proposals in Sept meeting?
Donald: that might be controversial (at this early stage).
6 oOptions for July/Sept down select combination was were presented by the Chair:
(1/4, 1/2)
(1/4, 1/3)
(1/4, MH)
(LH, 1/2)
(LH, 1/3)
(LH, MH)
Comment: Would like to add another option for no vote in July, MH in Sept (none, MH).
So total 7 options are presented for straw poll with only .11 voters.

The Chair suggested a motion to adopt General Pprocedures (Section 1), and rules for July/Sept (section 3, 4) but the consensus was to just have a straw poll to see if it is plausible that they will have over 75% support.

Result: Yes 26, no 0
11:40am: Go to tTechnical presentation "Ripple: A Distributed Medium Access Protocol for Wireless Mesh Networks", 11-05/0334r0, while giving Juan Carlos time to clean up the document and keep only the adopted sections in 274 so TGs can vote on it later.

ú Decided to go with two nested loops, inner having two confirmation votes after both fail, pop back to the two highest ranked proposals. After three outer loops (6 total confirmation votes), TG must vote on a motion to recommend that it be dissolved.
