For baking I use the minus 25 deg. rule of thumb with the GE stove in
convection bake mode, and it seems to work out pretty well, at about the
same timing or a little less than with regular bake mode.

For roasting, I don't change the temp from recipe settings, but watch
the progress of the roasting and check with a thermometer when things
look "done".
