Im not a TeXnician or a Texacker, more a TeX kiddie [1] and looked only
the ConTeXt module where \placefloat is defined and searched for the
command which is responsible for the numbermechanism.

Me too.

Search for \preparefloatnumber in page-flt.tex

Try my example with checked and nochekced.

Hallo Wolfgang,

you can see a bad sideeffects by figurenumber=nocheck in my example

<example>

\setupfloats[numbering=nocheck]

\starttext

\placefigure{}{\framed{Blub}}

\placefigure[page][]{}{\framed{Bautz}}

\placefigure{}{\framed{Bla}}

This were \rawnumber[figure] figures by now!

\setnumber[figure]{8}

We want to count on with \rawnumber[figure].

\placefigure{}{\framed{Plong}}

figurenumber is incremented to \rawnumber[figure].

\stoptext

</example>

The number of the figures are set as they appear in the text and this
did not work well when one figure is set later as another one typed
later in your code.

Hope you can find a solution for your problem before I send you one
when I have time too find one.
