The Gene Cafe heater is either on or off, hence the five degree
fluctuations. It switches on or off depending on what your setting is
calling for.

There's another Gene Cafe roaster her in Grand Rapids who has wired his
variac directly to his heating element and it seems to work fine for him.
And his coffee tastes just fine.

As to profiles, play around, make small changes, keep notes, taste and make
more notes.
