I kill my Training if the Cycles are too slow, measured via timer() from INITRUN to EXITRUN.

There is a final cycle or two at the end of the Training phase. These cycles are special. They take a long time compared to the individual Training Cycles. Anyway, I'm willing to wait for them. Most of the costs of Training have already been spent by then.

I don't see how to distinguish them. TRAINMODE is true in both cases. At first I thought it was just the FACTORS run. But apparently there is another run after that, where parameter choices are being resolved. In that run, FACTORS is not set. How can I identify it? Through guess-and-check, I find it is possibly identified by

(is(TRAINMODE) and not is(FACTORS) and not is(RULES))

Yikes.
