Thanks very much for the hints & info. That's the sort of
thing I did for E6, with the whole lot sitting on an ancient
second-hand warming plate meant for developing dishes.

Did you presoak the film & tank in water to get the
temperature roughly right first? That's what I used to do
with B&W and E6. Otherwise adding the developer to a
tank+film at a different temperature would give a
temperature which would never be quite right inside a mere
3-minute period.

I'm concerned that with such a short development time, it
will be difficult to keep the temperature of the actual film
reasonably near the specification without a presoak,  but
that the presoak, by pre-swelling the emulsion, might alter
the result anyway.

I suppose the fact that you've succeeded demonstrates that
it's not that critical, and what I should do is try it and
see (as usual <G>).
