<p>Hi Mark</p>
<p>Although not anywhere conclusive I made a Mapillary capture
outbound on Woore Street Wilcannia 5/2022 that shows what are
likely to be the dual 50/100 transition signs (smudges) well
before the changeset. Might be useful..</p>

I haven’t done any reversions yet. I was planning to start from
the oldest changeset and work forwards, however the oldest
changesets don’s specify a source. I’ve asked about a couple of
these including:

of Old Junee</div>
<div><br>
</div>
<div>Both of these are claimed to be from information provided by
’someone’ who had travelled on those roads. I’ve just asked for
more info regarding the source of this information.</div>

reason I ask is that I recently
came across a few roads with speed
zones updated based on this data.
The biggest problem is that the
changes made in these three
changesets were incorrect (i.e.
the previously surveyed maxspeeds
were updated from this data, but
on survey in December 2023 the
original surveyed maxspeed was the
correct one). </div>
