I am dumping a bit of analysis here which will probably be a boring read and perhaps hard to grasp.
This is mainly for my own records.
The background is the fact that AE911T has focused on architecture conventions in the last two years, where they tried to collect on-paper signatures to add to their Petition. They have variously said that they got more than 100 new signatures here and >100 sigs there - and I have previously reported that those numbers did not appear in the online petition, even after many months.
So I decided to look back how the number of "Licensed Architects" increased compared to all others, and to estimate how many "paper" signatures have been added to the online listing.
In February 2011 (an arbitrary "long ago" starting point), the petition had 1434 signatures. 235 of these, or 16.4%, were "Licensed Architects".
In the almost four following years, that percentage dropped to 14.5% (334 of 2308 on December 01, 2014). What happened there is that, while the number of engineers increased by about 60% and the number of non-US signatories by over 80%, the number of architects increased by only 42%.
It seems that Gage, being an AIA architect, had relatively more success with architects in the earlier years of his endeavour: By 2011, he appeared to have signed more than 0.1% of the AIA and of the licensed architects, but hardly 0.02% of the licensed engineers, for example. It seems natural that he would struggle to keep up those rates.
At the 2015 AIA Convention, always held in spring, they announced they had signed >150 new "members", but half a year later, only 6 new licensed architects appeared online - +1.8%, compared to 1.7% for the entire list. This was a time when they simply did not verify new signatures for 5 straight months.
And so it were that on 01 December 2015, the licensed architects were 14.4% of the total signatories - near an all-time low.
Since then, the licensed architects have increased by 53.8%, while all other signatures increased by only 14.5%. The growth rate of the architects exceeds that of all other categories by a factor of 3.7.
The absolute increase was +185 signatures (from 344 to 529).
It seems obvious that the bulk of these are the paper-signatures collected at conventions since spring 2015.
Had the number of architects increased at the same rate as the other categories, they would have picked up 50 new licensed architects (14.5% of 344).
The difference: +185-50 = 135 signatures, is a good first estimate of the number of paper-signatures from 2 years worth of architecture conventions.
There have been 3 AIA Conventions since 2015, and several other architecture conventions, and at least 3 times they claimes to have signed up >100 people. Sounds like 400-500 signatures - but only a third of that is actually there.
On 11/23/2016, I quoted a news item, saying that they had won 100+ supporters for their 2017 AIA resolution proposal. I have checked the names that appeared on the resolution pamphlet they mailed in December:

They list 173 AIA members by name, but only 40% of these appear on the online Petition today.
